Question

A car accelerate uniformly from 18 km/h in 5 sec. Calculate(i) the acceleration.​

Answer 1

Answer:

Given,

u=18km/h=

60×60

18×1000

=5m/s

v=36km/h=

60×60

36×1000

=10m/s

t=5sec

acceleration, a=?

1st equation of motion,

v=u+at

10=5+5a

5a=5

a=

5

5

=1m/s

The correct option is A.
