A fireworks rocket explodes at height h, the peak of its vertical trajectory. It throws out burning fragments in all directions, but all at the same speed v. Pellets of solidified metal fall to the ground without air resistance. Find the smallest angle that the final velocity of an impacting fragment makes with the horizontal.
You're in an airplane that flies horizontally with the speed of 900 km/h (250m/s) when an engine falls off. Neglecting air resistance assume it takes 34 seconds for the engine to hit the ground. If the airplane somehow continues to fly as if nothing has happened what is the distance between the engine and the airplane at the moment the engine hits the ground?
A ball is thrown from the top of a tower at an angle of 40o to the horizontal with an initial speed of 6.60 m/s. During its flight, the only force acting on the ball is the force of gravity. It takes 3.55 s until the ball hits the ground. How tall is the tower?
An athlete can jump to a height of 2.0 meters leaving the ground at an angle of θ = 60.0◦ to the horizontal. What is the magnitude of the athlete’s velocity at the moment the athlete leaves the ground (ignore the person’s size/shape).
A 480g falcon can reach high speeds near the ground after vertically diving from heights approaching 200m after starting with a zero (vertical) speed. Calculate such speed after assuming the falcon speeding up under the influence of gravity only. Answer a) 0.00m/sAnswer b) 62.6m/sAnswer c) 75.0m/sAnswer d) 200m/s
The shot put is a track-and-field event in which athletes throw a heavy ball - the shot - as far as possible. The best athletes can throw the shot as far as 23 m . Athletes who use the "glide" technique push the shot outward in a reasonably straight line, accelerating it over a distance of about 2.0 m . What acceleration do they provide to the shot as they push on it? Assume that the shot is launched at an angle of 37 degrees, a reasonable value for an excellent throw. You can assume that the shot lands at the same height from which it is thrown; this simplifies the calculation considerably, and makes only a small difference in the final result.
The great, gray-green, greasy Zambezi River flowsover Victoria Falls in south central Africa. The falls are approximately 108 m high. If the river is flowing horizontally at 3.60 m>sjust before going over the falls, what is the speed of the water whenit hits the bottom? Assume the water is in free fall as it drops.
A projectile is fired with an initial velocity of 320m/s at an angle of 15o with the horizontal. Find the velocity, in m/s, of the projectile along the horizontal after 10s. the answer should be 3 decimal places.
A rock is throw horizontally off a 100 m cliff with an initial velocity of 11 m/s. What is the angle of the rock's velocity with respect to the horizontal when it hits the ground. (Enter the answer as a positive angle without units.) Assume g=10m/s/s.
A place-kicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 20.4 m/s at an angle of 50.0° to the horizontal. By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.)
A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 23.8 m/s at an angle of 52.0° to the horizontal. By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short.)
