Question

A bus starting from rest moves with a uniform acceleration of 0.1 ms-2 for 120 second. Find (a) the velocity acquired. (b) the distance travelled.

Answer 1

Answer:

u=0m/s (bcoz body is at rest)

a=0.1m/s²

t=120 sec

v=u+at

=0+0.1×120m/s

=12m/s

s=ut+1/at²

=0×120+1/2×0.1×(120)²

=1/2×12×120

=6×120=720m

so, velocity=12m/s and distance=720m.
