Velocity of a vehicle increases from 5ms to `15 ms^(-1)` in 5 s. What is the magnitude of acceleration ?

A

` 4m s^(-2)`

B

`4ms^(-1)`

C

`2ms^(-1)`

D

`2ms^( -2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Acceleration `= ("Change in velocity")/("Time interval")= ((15 - 5) ms ^(-1)) /(5s) = 2ms ^(-2)`
