Question

A 200,000g bus is gaining speed from 5 m/s to 25 m/s during the first 10s of its journey. What force did the bus need to accelerate?

Answer 1

Answer:

mass=200,000g

=200,000/1000

=200kg

u=5m/s

v=25m/s

t=10sec

a=(V-U)/T

=(25-5)/10

=2m/s²

force=mass× acceleration

f=200×2

f=400n
