A ball was thrown vertically downward from a 50-m high building with an initial speed of 5m/s. What is the magnitude of the acceleration after 1.0s?

tortoise crawls the entire 1000.0 meters at a speed of 0.20 m/s. The rabbit runs the first 200.0 meters at 2.0 m/s, stops to take a nap for 1.3 hours, and awakens to finish the last 800.0 meters with an average speed of 3.0 m/s. Who wins the race and by how much time? Get to destination at the same time. Rabbit wins by 47 s Tortoise wing by 47 s O rabbit wins by 2.02 hrs Tortoise wins by2.02 hours

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?

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?

An airplane starts from rest and accelerates at a constant 3.38 m/s2 for 30.32 s before leaving the ground. What is its displacement during this time?

A train, traveling at a constant speed of 25 m/s, comes to an incline with a constant slope. While going up the incline, the train slows down with a constant acceleration of magnitude 1.8 m/s2. What is the speed of the train after 8.0 s on the incline?

A zombie is playing catch with his zombie friend's head. It throws up in the air with an inital velocity of 26.2 m/s. How long until the zombie head reaches the maximum height? how far?

A driver applies the brakes on his car reducing its speed from 31.0 m/s to 11.0 m/s in a time 5.0 secs while traveling a distance of 121 m. What is that magnitude of the car's average acceleration during the 5.0 sec period?
