Question

A car of mass 1000kg starting from the rest achieves a velocity of 50m/s in 5 seconds. Calculate it's acceleration and distance travelled.​

Answer 1

Answer:

a = 10 m/s^2

s = 125 m

Explanation:

m = 1000kg

u = 0 m/s (started from rest)

v = 50 m/s

t = 5 s

a = (v - u)/t

= (50 - 0)/5

= 50/5

a = 10 m/s^2

s = ut + 1/2 at^2

= (0 x 5) + 1/2 x 10 x 5^2

= 5 x 25

s = 125 m
