Question

How much time will it take a scooter accelerating at 0.400 m/s2 to go from rest to a velocity of 4.00 m/s?

A. 10 seconds
B. 15 seconds
C. 20 seconds
D. 25 seconds

Answer 1

The scooter will take 10 seconds to go from rest to a velocity of 4.00 m/s.

Step-by-step explanation:

To find the time it takes for the scooter to accelerate from rest to a velocity of 4.00 m/s, we can use the formula:

v = u + at

Where v is the final velocity, u is the initial velocity (0 since the scooter is at rest), a is the acceleration (0.400 m/s2), and t is the time.

Plugging in the known values, we have:

4.00 = 0 + (0.400)t

Solving for t, we get:

t = 4.00 / 0.400 = 10 seconds

Therefore, it will take 10 seconds for the scooter to go from rest to a velocity of 4.00 m/s.
