4 A roller coaster car begins its roll from the top of the tracks at a speed of
2 meters per second. When it reaches the bottom of the 200-meter drop
four seconds later, its speed is 22 meters per second. What was the average
speed of the roller coaster ride in meters per second over the 200-meter drop?

50 m/s

Explanation:

The motion of the roller coaster car parameters are;

The initial speed of the roller coaster, v = 2 m/s

The distance to reach the bottom, Δd = 200 meter

The time it takes to reach the bottom, Δt = 4 seconds

The speed at the bottom of the tracks = 22 m/s

The average speed, = Δd/Δt

∴ = (200 m)/(4 s) = 50 m/s

The average speed of the roller coaster ride over the 200 m drop, = 50 m/s

answer: a ball

explanation: because it will bounce
