A car is traveling at 30 m/s. The driver applies the brakes, and the car uniformly decelerates at 9 m/s2. How far does the car travel before coming to a complete stop?
A rock is pushed from rest across a sheet of ice, accelerating at 2.0 m/s2over a distance of 20 cm. The rock then slides at a constant speed for 15.0 s until it reaches a rough section that causes the rock to stop in 5.5 s. (Assume two significant digits.
A person drops a stone down a well and hears the echo 8.9 s later. If it takes 0.9 s for the echo to travel up the well, approximately how deep is the well?
From rest, a ball is dropped from the top of a building. It takes 4 s to hit the ground. Approximately how tall is the building?
A car is traveling at an unknown velocity. It accelerates constantly over 5.0 seconds at a rate of 3.0 m/s2 to reach a velocity of 30 m/s. What was the original velocity of the car
A car in a drag race started from rest and accelerated constantly to a velocity of 50 m/s when it reached the end of a 500-m road. What was the car's rate of acceleration?
A plane takes off from rest and accelerates constantly at a rate of 1.0 m/s2 for 5 minutes. How far does the plane travel in this time?
If you drop a ball from a 100-m-tall building, approximately how far will the ball fall in 2 s?
An ice skater moving at 10 m/s comes to a complete stop in 0.5 s. What is the rate of acceleration?
A person drops a stone down a well and hears the echo 8.9 s later. If it takes 0.9 s for the echo to travel up the well, approximately how deep is the well?
