A ball is thrown vertically downwards with a speed 7.3 m/s from the top of a 51 m tall building. With what speed will it hit the ground, in units of m/s? Assume that air resistance is negligible Glue the answer as a positive number
An object is thrown directly downward from the top of a very tall building. The speed of the object just as it is released is 29.3 m/s. After being thrown, the object falls freely due to gravity. Neglect air resistance and calculate the distance, in meters which the object covers between times t1 = 1.77 s and t2 = 5.02 s after it is thrown.
A 0.26-kg rock is thrown vertically upward from the top of a cliff that is 32 m high. When it hits the ground at the base of the cliff, the rock has a speed of 33 m/s . Part A Assuming that air resistance can be ignored, find the initial speed of the rock.(Express your answer using two significant figures.) Part B Find the greatest height of the rock as measured from the base of the cliff. (Express your answer...
it A stone is thrown from the top of a tall cliff. Its acceleration is a constant -32 2 sec (So A(t) = -32). Its velocity after 3 seconds is 25 ft sec and its height after 3 seconds is 247 ft. Find the velocity function. v(t) = Find the height function. h(t)
An object is thrown vertically upwards with initial speed 15m/s. After 1s, a second object is thrown up. What is the initial speed that the second object must have to hit the first object at a height of 11m?
Two rocks are thrown from the top of a very tall tower. One of them is thrown vertically up with an initial velocity of Vup=19.7 m/s. The other rock is thrown horizontally to the right with an initial velocity of Vright 12.7 m/s. (See figure.) How far will the rocks be from each other after 2.76 s? (Neglect air resistance and assume that the rocks will not hit the ground or the tower.)
An object is dropped from the top of a tall building. How far does it fall during the fifth and sixth seconds?
An object is thrown straight downwards at 7 m/s from the top of a water well. If the water we is 72 meters deep, how long, in seconds, does it take the object to hit the bottom of the Well?
Two rocks are thrown from the top of a very tall tower. One of them is thrown vertically up with an initial velocity of Vup -15.6 m/s. The other rock is thrown horizontally to the right with an initial velocity of Vright -10.3 m/s. (See figure.) V. up V. right How far will the rocks be from each other after 4.11 s? (Neglect air resistance and assume that the rocks will not hit the ground or the tower.) Subt Ane...
Question 3 1 pts A rock is thrown upward from the edge of a cliff that is 20 m high. The object rises 15 m and then falls to the ground. If the positive direction of the x is up, what is the rock's displacement? O 20 m 0-15 m -20 m O 55 m Question 4 1 pts A 4.4-kg mass is falling starting from rest at a height of 22 m. How much time does it take for...
