Question

a scooter moving at a speed of 10 m/s is stopped by applying brakes which produce a uniform acceleration of 0.5 m/s, find the distance covered by the scooter before it stops?

Answer 1

u=10m/s a=-0.5m/s^2 v=0m/s s=?

v^2=u^2+2as
0=100+2(-0.5)s
s=100m

Answer 2

apply v^2= u^2 + 2.g.s
g= -0.5
v= 0
u= 10 m/s
hence s i.e distance will be 100 m
