Question

A body start up from rest and
acquires a velocity of 8ms' in 5s.
Calculate
(a) the acceleration
(b) the distance covered in 5s
(c) the distance covered in 5th second.
(a) 1.6 ms”. (b)20 m, (c)7.2m​

Answer 1

Answer:

v = 8m/s , u = 0

s = 5s

a = (v - u)/ t

a = (8 - 0)/ 5

a = 8 / 5

a = 1.6m/s²

8 = 5 ÷ d

d = 8 × 5

d = 40m in 5second
