A motorcycle is moving at $30 \mathrm{~m} / \mathrm{s}$ when the rider applies the brakes, giving the motorcycle a constant deceleration. During the $3.0 \mathrm{~s}$ interval immediately after braking begins, the speed decreases to $15 \mathrm{~m} / \mathrm{s}$. What distance does the motorcycle travel from the instant braking begins until the motorcycle stops?

Step 1
First, we need to find the deceleration of the motorcycle. We can use the formula: $a = \frac{v_f - v_i}{t}$, where $a$ is the deceleration, $v_f$ is the final velocity, $v_i$ is the initial velocity, and $t$ is the time interval. Show more…

A motorcycle is moving at 30 m/s when the rider applies the brakes, giving the motorcycle a constant deceleration. During the 3.0 s interval immediately after braking begins, the speed decreases to 15 m/s. What distance does the motorcycle travel from the instant braking begins until the motorcycle stops?

Distance. A motorcycle accelerates at a constant rate from 0 to 50 mph in 15 sec. How far does it travel during that time?

A car is traveling on a straight road at a constant 30 m/s m / s , which is faster than the speed limit. Just as the car passes a police motorcycle that is stopped at the side of the road, the motorcycle accelerates forward in pursuit. The motorcycle passes the car 12.5 s s after starting from rest. How far does the motorcycle travel before it passes the car?
