The longest Home Run. According to Guinness World Records, the longest home run ever measured was hit by Roy “Dizzy” Carlyle in a minor league game. The ball traveled 188 m (618 ft) before landing on the ground outside the ballpark, (a) If the ball’s initial velocity was in a direction 45° above the horizontal, what did the initial speed of the ball need to be to produce such a home run if the ball was hit at a point 0.9 m (3.0 ft) above ground level? Ignore air resistance, and assume that the ground was perfectly flat, (b) How far would the ball be above a fence 3.0 m (10 ft) high if the fence was 116 m (380 ft) from home plate?

Introduction to Electrodynamics
- In 2004 two Martian probes successfully landed on the Red Planet. The final phase of the landing involved bouncing the probes until they came to rest (they were surrounded by protective inflated “balloons”). During one of the bounces, the telemetry (electronic data sent back to Earth) indicated that the probe too off at 25.0 m/s at an angle of 20 degrees and landed 110 m away (and then bounced again). Assuming the landing region was level, determine the acceleration due to gravity near the Martian surface.arrow_forwardAccording to the Guinness Book of World Records the longest home run evermeasured was hit by Roy “Dizzy” Carlyle in a minor league game. The ball travelled188 m (618 ft) before landing on the ground outside the ballpark. (a) Assuming theball’s initial velocity was in the direction of 450 above the horizontal and ignoringresistance, what did the initial speed of the ball need to be to produce such a homerun if the ball was hit in a point 0.9 m above ground level? Assume that the groundwas perfectly flat. (b) How far would the ball be above a fence 3.0 m high the fencewas 116 m from home plate?arrow_forwardMessi is keeping his free-kick skills sharp this quarantine by playing football with his neighbour's monkey.From the roof of his house, which is 7 meters above the ground, he kicks a ball horizontally towards his neighbour'shouse, which is 6 meters away and also has a roof that is 7m above the ground. At the same instance, his neighbour'spet monkey drops off the ledge of his roof to try to catch the ball. Please ignore air resistance, and take g=9.81m/s2 If Messi kicks the ball with the minimum required speed; at what time (in seconds) after the kick is the monkey able to catch the ball?The minimum speed (in m/s) is 5.023.arrow_forward
- Problem 8: A baseball slugger hits a pitch and watches the ball fly into the bleachers for a home run, landing h = 5.5 m higher than it was struck. When visiting with the fan that caught the ball, he learned the ball was moving with final velocity vf= 38.7 m/s at an angle 6f = 33° below horizontal when caught. Assume the ball encountered no air resistance, and use a Cartesian coordinate system with the origin located at the ball's initial position. yarrow_forwardIn a carnival booth, you win a stuffed giraffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal distance of 2.1 m from this point. If you toss the coin with a velocity of 6.4 m/s at an angle of 60° above the horizontal, the coin lands in the dish. You can ignore air resistance,a) What is the height of the shelf above the point where the quarter leaves your hand? b) What is the vertical component of the velocity of the quarter just before it lands in the dish?arrow_forwardCan you help me with this question? A motocyclist drives his bike off of a 12 m high horizontal ledge. If he is driving at a speed of 22 m/s horizontally, how far from the base of the ledge does he land?arrow_forward
- At serve, a tennis player aims to hit the ball horizontally (Figure 1). What minimum speed is required for the ball to clear the 0.90-mm-high net about 15.0 mm from the server if the ball is "launched" from a height of hhh = 2.30 mm ? Express your answer to three significant figures and include the appropriate units.arrow_forwardMeasurements of a shot recorded on a videotape during a basketball game are shown below. The ball passed through the hoop even though it barely cleared the hands of the player B who attempted to block it. Neglect the size of the ball. I need help in finding the magnitude of the ball's initial velocity vA and the height h of the ball when it passes over player B please show complete solution, thanks.arrow_forwardA ball is thrown from the edge of a cliff of height h=100 m with an initial horizontal velocity of Vy=10 m/s. a) How long does it take for the ball to reach the ground? b) How far has the ball traveled in the x direction when it hits the ground? c) What is the balls final velocity vector when it hits the ground? (Component form) d) What are the magnitude and direction of the ball's velocity when it hits the ground? (Polar form)arrow_forward
- A projectile is fired horizontally with an initial speed of 50 m/s. Neglect air resistance. What is the speed of the projectile 3 seconds after it is fired?arrow_forward1. A player lines up to kick a 40 m goal. In the first attempt, the ball has an initial velocity of 20 m/s at angle of 55.0 degrees. The goal posts are 3 m high. Ônce the ball passes above the field goal post (i.e., after it has travelled 40 m in the horizontal direction), it is deemed successful. (a) Determine if the goal kicker's first attempt is successful. (b) If the kicker changes the angle of kicking to 30 degrees and the initial velocity so that it JUST reaches the goal post. Determine the new initial velocity of ball.arrow_forwardThe projectile shown in the figure below is fired att = 0 seconds with an initial speed of 160ft/s at an angle of 53 o above the horizontal axis. Use g = 32.0 ft/s 2 .(a) Find its position vector at t = 2.00 s(b) Find the velocity of the particle att = 2.00 seconds.(c) Find the maximum height H, and the time to reach this point.(d) Find the horizontal range R.(e) What is the acceleration of the projectile at the highest point?(f) With what velocity does it hit the ground?arrow_forward
