Question

The velocity of a motorcycle increases by an acceleration of 2ms-2 and becomes 20ms-1 in 5 seconds. find the initial velocity of the car.​

Answer 1

Explanation:

The velocity of a motorcycle increases by an acceleration of 2ms-2 and becomes 20ms-1 in 5 seconds. find the initial velocity of the car.

Answer 2

Answer:

10 m/s

Explanation:

a= 2 m/s² , v = 20 m/s , t= 5 s , u =?

According to the First Law of Motion ,

v = u + at

Putting values ,

20 = u + 2 × 5

20 = u + 10

u = 20 - 10

u = 10 m/s

Thus the initial velocity of the car is 10 m/s
