Question

A child sleds down a steep, snow covered hill for 547 meters. If her initial speed is 0.0 m/s and her final speed is 15.5 m/s, what is her rate of acceleration? Options: • 0.0 m/s^2 • 1.5 m/s^2 • 7.7 m/s^2 • 15.5 m/s^2

Answer 1

To find the rate of acceleration, use the formula (final velocity - initial velocity) / time. Calculate the time it took using the distance formula and then solve for acceleration.

Step-by-step explanation:

To find the rate of acceleration, we can use the formula:

acceleration = (final velocity - initial velocity) / time

Since the initial speed is 0 m/s, we can calculate the time it took for the child to sled down the hill using the formula:

distance = (final velocity + initial velocity) / 2 * time

Substituting the given values, we can solve for time and then substitute it into the first formula to find the rate of acceleration.
