A student at the top of a building of height h throws one ball upward with a speed of vi and then throws a second ball downward with the same initial speed vi. Just before it reaches the ground, is the final speed of the ball thrown upward (a) larger, (b) smaller, or (c) the same in magnitude, compared with the final speed of the ball thrown downward?
You're playing a cartoony racing video game, with a character on a motorcycle. You drive your character off a ledge at 15 m/s. The next ledge for the character's bike to land on is 25 m away (horizontally) and 12 m below. Assume the video game has realistic physics coded into it, except that acceleration due to gravity is only 8.0 m/s^2. a) will your character land on the next platform? b) whether they land or not, find their velocity (magnitude and direction) as they either land on or pass through the 12 m below position.
•• I P A white-crowned sparrow flying horizontally with a speed of 1.80 m/s folds its wings and begins to drop in free fall. How far does the sparrow fall after traveling a horizontal distance of 0.500 m? If the sparrow’s initial speed is increased, does the distance of fall increase, decrease, or stay the same? Graph and solve .
A man flies a small airplane from Fargo to Bismarck, North Dakota --- a distance of 180 miles. Because he is flying into a headwind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 hour and 30 minutes. What is the plane's speed in still air, and how fast is the wind blowing?A. his plane speed equals mph.? B. the wind speed equals mph.?
A spacecraft is observed to be at a location < 200 , 300 , -400 > m relative to an origin located on a nearby asteroid, and 5 seconds later is observed to be at location < 340 , 80 , -540 > m. (a) What is the average velocity of the spacecraft during this interval?v→avg = m/s (b) What is the average speed of the spacecraft during this period?|v→avg|= m/s (c) What is the unit vector in the direction of the average velocity?v^=
A glider is initially moving at a constant height of 3.76 m. It is suddenly subject to a wind such that its velocity at a later time t can be described by the equation v(t) = 16.18 − 7.78(1 + t) + 0.70t3, where v and its components are in meters per second, t is in seconds, and the z axis is perpendicular to the level ground. (a) What was the initial velocity of the glider? (Express your answer in vector form.) vi = m/s(b) Write an expression for the acceleration of the glider in component form when t = 2.14 s. (Express your answer in vector form.) a(t = 2.14 s) = m/s2
A man was standing on one side of the roof of a building 145 meters above the ground and shot a projectile with O HO oti av. ta an initial speed of 53 m/s at an angle of 30° with the horizontal. Find: a) the time ( seconds) it took the projectile to hit the ground b) how far (meter) away from the base of the building did the projectile land? c) Find the vertical and horizontal components of the velocity (m/s) d) what is its velocity in m/s
A Chinook (King) salmon (Genus Oncorynchus) can jump out of water with a speed of 6.73 m/s. (See Problem 4.9, page 111 for an investigation of how the fish can leave the water at a higher speed that it can swim underwater.) If the salmon is in a stream with water speed equal to 1.55 m/s, how high in the air can the fish jump if it leaves the water traveling vertically upwards relative to the Earth? m
In 1780, in what is now referred to as “Brady’s Leap,” Captain Sam Brady of the U.S. Continental Army escaped certain death from his enemies by running horizontally off the edge of the cliff above Ohio’s Cuyahoga River, which is confined at that spot to a gorge. He landed safely on the far side of the river. It was reported that he leapt 22 ft across while falling 20 ft. Tall tale, or possible?a. What is the minimum speed with which he’d need to run off the edge of the cliff to make it safely to the far side of the river?b. The world-record time for the 100 m dash is approximately 10 s. Given this, is it reasonable to expect Brady to be able to run fast enough to achieve Brady’s leap?
A mountain climber jumps a crevasse of width W by leaping horizontally with speed V0. If the height difference between the two sides of the crevasse is h, what is the minimum value for the climber to land safely on the other side? In this case, what is the climber’s direction of motion landing? Graph and solve for the answer.
The cannon on a battleship can fire a shell a maximum distance of 36.0 km. (a) Calculate the initial velocity of the shell.(b) What maximum height does it reach? (At its highest, the shell is above a substantial part of the atmosphere--but air resistance is not really negligible as assumed to make this problem easier.)(c) The ocean is not flat since the earth is curved. How many meters lower will its surface be 36.0 km from the ship along a horizontal line parallel to the surface at the ship? Does your answer imply that error introduced by the assumption of a flat earth in projectile motion is significant here? (Select all that apply.) The error is insignificant compared to the distance of travel. The error is significant compared to the distance of travel. The error could be significant compared to the size of a target. The error is insignificant compared to the size of a target.
