Question

A bear is sitting at rest on a tricycle. The bear then starts to accelerate uniformly at a rate of 2.5 m/s2 (meters per second square). How long will it take the bear to reach a velocity of 15 m/s (meters per second)

Answer 1

6.0 s

Step-by-step explanation:

Given:

u = 0 m/s

v = 15 m/s

a = 2.5 m/s²

Find: t

v = u + at

15 = 0 + (2.5) t

t = 6.0 s
