Concept explainers
There are competitions in which pilots fly small planes low over the ground and drop weights, trying to hit a target. A pilot flying low and slow drops a weight; it takes 2.0 s to hit the ground, during which it travels a horizontal distance of 100 m. Now the pilot does a run at the same height but twice the speed. How much time does it take the weight to hit the ground? How far does it travel before it lands?

- A stone is thrown at 16 m/s with an angle of 40° above the horizontal from the rooftop of the building 56 m above the ground. How long will it take for the stone to reach the ground?  What is the velocity of the stone just before it strikes the ground?arrow_forwardA stone is thrown horizontally off a 25 m high building. It hits the ground a distance of 20 m from the foot of the building. What is the initial velocity of the stone?arrow_forwardAn attacker at the base of a castle wall 3.67 m high throws a rock straight up with speed 8.10 m/s at a height of 1.53 m above the ground. Will the rock reach the top of the wall? what is the rock's speed at the top? If not, what initial speed must the rock have to reach the top?  Find the change in the speed of a rock thrown straight down from the top of the wall at an initial speed of 8.10 m/s and moving between the same two points.arrow_forward
- A boy throws a stone horizontally with an initial speed of 20 m/s from the edge of a cliff. A stop watch measures the stone's trajectory time from the top of the cliff to the bottom to be 5.0 s. (a) What is the height of the cliff? (b) How far does the stone travel horizontally? (c) What is the total acceleration of the stone while it is in the air?arrow_forwardAt the edge of a cliff, a rock is thrown with an initial velocity of 18m/s at a 15 degree angle above the horizontal. If the rock is thrown from 25m above the cliff’s base, how long will it take to reach the ground the moment it is released?arrow_forwardAn egg is thrown horizontally off the roof of a tower, which is 60 meters high, with an initial velocity of 6.5ms . How long does it take to hit the ground? How far does it go in the r direction?arrow_forward
- Suppose you are standing on a ladder and holding a ball 5 meters above the ground. You throw the ball upwards with a speed of 15 m/s. How long will it take the ball to hit the ground?arrow_forwardA gazelle runs off the edge of a cliff. He is launched horizontally with a velocity of 34m/s. The cliff is 20 meters tall. How much time will it take to hit the ground?arrow_forwardA piano has been pushed to the top of the ramp at the back of a moving van. The workers think it is safe, but as they walk away, it begins to roll down the ramp. If the back of the truckis 1.0 m above the ground and the ramp is inclined at 20°, how much time do the workers have to get to the piano before it reaches the bottom of the ramp?arrow_forward
- A lifeguard stands on top of a watch tower at the beach and purposely throws a stone horizontally with a speed of vi=18.0 m/s. The height of the tower is 50.0 m above the ground.  With what speed does the stone land? How long after being released does the stone strike ground? With what angle of impact does the stone land?arrow_forwardJenny and Jack throw identical balls off a tall building at the same time. The ground near the building is flat. Jenny throws her ball straight downward. Jack throws his ball downward and outward such that the angle between the initial velocity of the ball and the horizon is 30°. Jack throws the ball with a speed twice that of Jenny's ball. If air resistance is negligible, which ball hits the ground first? Jenny's ball hits first. It is impossible to know from the information given. Jack's ball hits first. They hit at the same timearrow_forwardA rock was thrown horizontally from a 146 m high cliff. It strikes the ground 97 m from the base of the cliff. At what speed was it thrown? A 19.9 m/s 17.8 m/s 18.3 m/s D 16.3 m/sarrow_forward
