Question

A car initially at rest starts moving with a constant acceleration of 0.05m/s and travels a distance of 25m. Find its final velocity andvthe time taken

Answer 1

Given,
u = 0
a = 0.05m/s
s = 25m
So, v2 = u2 + 2as
v2 = 2as
v2 = 2*0.05* 25
v2= 2.5
v = 1.5 m/s
Now,
v = u+ at
1.5 = 0.05t
t = 1.5/ 0.05
t= 30 sec.
