Question

A roller coaster starts from rest at the top of a drop and accelerates at a rate of 5.0 m/s2 for 2.0 sec. When it

Answer 1

Answer: 2.5 m/s.

Explanation:

At rest, acceleration = 0

At the top of the drop acceleration = 5.0 m/s2

Rate of acceleration = (5.0 m/s2 - 0) = 5.0m/s^2

Time taken for travel = 2.0 sec

At the bottom of the drop point, the velocity will be (Change in acceleration / time taken)

i.e (5.0 m/s2 / 2.0 seconds)

= 2.5 m/s

Thus, the velocity of the rollercoaster will be 2.5m/s.
