Question

multiple choice question during a straight line roller coaster ride, the coaster steadily climbs up a large hill, then rolls down the hill and constantly changes speed as it quickly goes up and down smaller hills until the end of the ride when the coaster slowly comes to a complete stop. choose the true statement from below. the instantaneous acceleration will be greatest during the end when it comes to a stop. the instantaneous acceleration will be greatest on the hills during the ride after reaching the top of the first hill. the instantaneous acceleration will be greatest in the initial ascent up the large hill at the beginning of the ride. the acceleration during the ride is constant.

Explanation:

Instantaneous acceleration is the rate of change of speed. When the coaster rolls down the first hill after the initial ascent, gravity acts to increase its speed rapidly, creating a large positive acceleration. When stopping at the end, acceleration is negative (deceleration) but not the greatest in magnitude compared to the downhill acceleration. The initial ascent has steady, small acceleration, and acceleration changes throughout the ride so it is not constant.

Answer:

C. The instantaneous acceleration will be greatest on the hills during the ride after reaching the top of the first hill.
