Kinematic closure

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

A boat travels 12.0 m while it reduces its velocity from 9.5 m/s to 5.5 m/s. What is the magnitude of the boat’s acceleration while it travels the 12.0 m?

• 1.3 m/s²
• 2.5 m/s²
• 3.0 m/s²
• 7.5 m/s²

The unit we use to measure acceleration is ___.

• m/s

• m

• s

• m/s²
