A cyclist, with the help of gravity, speeds up as he goes downhill on a straight part of the trail. His velocity changes from 1 meter per second at the top of the hill to 6 meters per second by the time he reaches the bottom. If it takes him 5 seconds to reach the bottom, what is his average acceleration as he races down the hill?
A car increases it’s velocity from 0 m/s to 14 m/s in 2 seconds. What is it acceleration?
A bicycle rider increases his speed from 5 m/s to 15 m/s in 10 seconds. What is her acceleration
A racing car’s velocity is increased from 44 m/s to 66m/s in 11 seconds. What is the cars acceleration?
A plane starting from rest is accelerated to its takeoff velocity of 75 m/s during a 5 second period. What is the planes acceleration?
