Kinematic Equations Practice

A car is traveling to the right with a speed of 29​​m/s when the rider slams on the accelerator to pass another car. The car passes in 110 m with constant acceleration and reaches a speed of 34m/s. We want to find the acceleration of the car as it sped up. What equation should you choose?

• v=v_o+at

• d=v_ot+1/2at²

• v²=v_o²+2ad

• d=1/2(v+v_o)t

If Michael Jordan has a vertical leap of 1.29 m, then what is his takeoff speed if his acceleration is -9.8 m/s² and his velocity at the top of his leap i 0 m/s?

• v=v_o+at

• d=v_ot+1/2at²

• v²=v_o²+2ad

• d=1/2(v+v_o)t

An engineer is designing the runway for an airport. Of the planes that will use the airport, the lowest acceleration rate is likely to be 3 m/s². The takeoff speed for this plane will be 65 m/s. All airplanes will start from rest. Assuming this minimum acceleration, what is the minimum allowed length for the runway?

• v=v_o+at

• d=v_ot+1/2at²

• v²=v_o²+2ad

• d=1/2(v+v_o)t
