A ball is thrown upward with an initial speed of 30 m/s. If it is subjected to an acceleration of - 10 m/s? a) How long does it take to reach the highest point of its trajectory? b) What is the maximum height it reaches?

3. In Physics, the height of a free-falling object at a given time t is given by h = –16t² + v,t + h., where v, is the initial velocity, and h, is the initial height. A student throws a ball upward from a height of 48ft, initially at 32 ft/s. What is the maximum height of the ball?

A ball is thrown vertically upward with a speed of 28.0 m/s. (a) How high does it rise? m(b) How long does it take to reach its highest point? s(c) How long does the ball take to hit the ground after it reaches its highest point? s(d) What is its velocity when it returns to the level from which it started? m/s

A ball is thrown upward at time t=0 from the ground with an initial velocity of 8 m/s (~ 18 mph). Assume that g = 10 m/s2. What is the greatest height (in meters) reached by the ball?

A rocket, initially at rest on the ground, accelerates upward with a constant acceleration of 94.0 m/s2 until it reaches a speed of 1.50E2 m/s when the engines are cut off. After that, the rocket is in free-fall. What is the maximum height reached by the rocket?

A ball is thrown upward at time t=0 from the ground with an initial velocity of 10 m/s (~ 22 mph). What is the total time it is in the air? Assume that g = 10 m/s2.

A ball is thrown vertically upward with a speed of 39.0 m/s. (a) How high does it rise? m(b) How long does it take to reach its highest point? s(c) How long does the ball take to hit the ground after it reaches its highest point? s(d) What is its velocity when it returns to the level from which it started? m/s

A rocket is fired straight up from rest with a net upward acceleration of 12 m/s2. After 10.0 s, the engine shuts off, but the rocket continues to coast upward with insignificant air resistance. What is the maximum the rocket reach from the ground?

I need help solving this question. A rocket starting from rest rises vertically and accelerates at a constant rate of 13 m/s2 for 7 min. At this point the engine of the rocket accidently fails and completely shuts down. (Neglect air resistance and any variation in the acceleration due to gravity) a) What is the speed of the rocket when the engine shuts down? b) How high is the rocket above the ground at the point where the engine shuts down? c) How much higher will the rocket rise after the engine fails? d) What is the total time of the rocket in air? e) What is the average speed of the rocket for the entire trip?

A rock is dropped off of a cliff. It takes 2.8s for the rock to reach the bottom. The acceleration due to gravity is 9.81 m/s2. How tall is the cliff?
