Question

Cyclist undergoes a uniform acceleration of 5.0 m/s square if its initial speed is 2.0 M/s how long does it take to reach a speed of 15.0 M/s

Answer 1

Answer:

2.6 seconds

Explanation:

a = 5 m/s square

u = 2 m/s

v = 15 m/s

t = ?

From first law of motion,

v = u + at

=> 15 = 2 + 5*t

=> 5t = 13

=> t = 13/5 = 2.6 s
