Question

A car travelling at 10m/so accelerates uniformly at 2 m/s square. calculate it's velocity after 5 seconds ​

Answer 1

Answer:

By first equation of motion,

v=u+at

=>v=10+2×5

=>v=20m/sec

Hence, the velocity of the car after 5 sec would be 20 m/sec.

Answer 2

Answer:

Given;-

intial speed=10m/s

acceleration=2m/s^2

time=5sec

To find :-

the velocity of the car after 5 sec

Formula:-

we know the terms

u=10m/s

a=2m/s^2

t=5sec

from equation

v=u+at

we can solve it

procedure:-

from equation ,v=u+at

v=10+2(5)

:.V=10+10

=20m/sec

:.hence, velocity after 5 sec is 20 m/sec
