Question

The train starts from rest and accelerates uniformly at 10m/s-2 for 1 minute.Find the velocity and distance​

Answer 1

Explanation:

train starts from rest u =0

u=initial velocity

v=final velocity. 1 minute=60 seconds

u=0

v=?

acceleration a=10m/s2

a= v-u/t.

a=v-0/60

a=v/60

a=10

10=v/60

v=10×60

v=600.

distance s=?

s=ut+1/2at2

=0+1/2×10×60×60

=5×3600

=18,000

distance s=18,000
