Question

A car acquires a velocity of of 12 kilometre per hour in 10 seconds starting from the rest find the acceleration the average velocity and the distance travelled in this time

Answer 1

Explanation:

Given -

u = 0m/s

v = 12 km / h = 12 ×5/18 = 3.34m/s

t = 10sec

a =?

s =?

v = u + at

3.34 = 0 + a×10

10a = 3.34

a =3.34/10

a = 0.334 m/s ^2

s = ut + 1 / 2 at^2

s = 0 x 10 + 1 / 2 × 0.334 ×10×10

s = 16.7 m
