Question

a body starts moving at velocity of 1.5ms after what time it will occur velocity of 15m s​

Answer 1

Appropriate Question:

A body starts moving with an acceleration of 1.5 m/s² . After what time , the body will reach the velocity of 15 m/s

Given :

• The acceleration = 1.5 m/s²
• Initial velocity = 0m/s
• Final velocity = 15 m/s
• time = ???

Formula to be applied:

• acceleration = (v-u)/t
• v = u+at
• t = (v-u)/a

Solution:

given, initial velocity = 0m/s

final velocity = 15m/s

acceleration = 1.5 m/s²

so, time = (v-u)/t

or, time = (15-0)/1.5

or, time = 15/1.5

or, time = 10 s

hence, the time taken to reach a velocity of 15m/s is 10 sec .
