Question

a car accelerate on a straight road from rest to a speed 180 km per hour in 25 s assuming uniform acceleration of car through out what is the distance covered in this time?

Answer 1

Hey

distance (s) =?

v^2 = u^2 + 2 as

a =?

a = v - u / t ; v = 50  m/s

= 50 - 0/ 25

= 50/25 = 2 m/s^2

v^2 = u^2 + 2 as

50^2 = 0^2 + 2 × 2 × s

2500 = 0 + 4s

4s = 2500

s = 2500/4

distance = 625 m
