Question

The car accelerates from rest v0 =0 m/s with the constant acceleration of a=4 m/s^2

for 3 seconds how far has the car traveled after three seconds

12 m

36 m

18m

6 m

Answer 1

Ans. Here

Initial velocity = u = 0 m/s (as it starts from rest )

Acceleration = a = 4 m/s^2

Time = t = 3 sec.

Distance traveled = s = ?

Using equation : s = ut + at^{​​​​​2}/2

s = 0 + 4 x3x3 /2

s = 18 m

Option C is correct
