Question

A car starts from rest and acquires the velocity of 50m/s after covering a distance of 1250m then
a' will be
(a) 1200m
b. 1 m/s
c. 10 m/s2
d. 30m/s?​

Answer 1

Answer:

(b) 1 m/s^2

Explanation:

Initial Velocity, u = 0 m/s

Final Velocity, v = 50 m/s

Distance, s = 1250 m

Acceleration, a = ?

v^2 - u^2 = 2as

2 × a × 1250 = 50 × 50

a = (50 × 50)/(2 × 1250) = 1

Acceleration, a = 1 m/s^2
