CBSE Class 9 Answered
a car has uniform acceleration of 8m/s². what distance will it cover in 20 s after starting from rest.?
Asked by fahmidafarooqui59 | 10 Jun, 2021, 13:20: PM
a = 8 m/s2
t = 20 s
s = ?
u = 0
s = ut + (1/2) at2
s = 0 + (1/2) x 8 x 202
= 4 x 400 = 1600 m
s = 1600 m
Thus, the distance that will be covered in 20s after starting from rest is 1600 m.
