A car is traveling at a velocity of 35.0 miles per hour. The car runs off a cliff that has an unknown height. The car 'lands' 50.0 meters from the base of the cliff.

How long would it take the car to 'land' after exiting the rim of the cliff? (use -10m/s² for g)

• About 1.5s

• About 3.0s

• About 3.5s

• About 1.0s

A car slows down from +32 m/s to +8 m/s in 4 s. The acceleration is

• -6m/s²

• 6m/s²

• -8m/s²

• 8m/s²

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
• Δx=v_ot+1/2at²
• v²=v_o²+2aΔX
• Δx=((v+v_o)/2)t

An airplane accelerates down a runway at 3.20 m/s² for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.
Which equation is appropriate?

• v=v_o+at
• Δx=v_ot+1/2at²
• v²=v_o²+2aΔX
• Δx=((v+v_o)/2)t
