A body moving with an initial velocity of 20m/s accelerates uniformly at a rate of 40m/s. What is the distance covered during this period?
A.
100m
B.
85m
C.
70m
D.
60m
Correct Answer: 60m
Explanation
Given: u= 20m/s, a = 10m/s, v = 40m/s, s=
using, = + 2as
= + 2 10 s
1600 = 400 +20s
1600 - 400 = 20s
1200 = 20s
s = 60m
Given: u= 20m/s, a = 10m/s, v = 40m/s, s=
using, = + 2as
= + 2 10 s
1600 = 400 +20s
1600 - 400 = 20s
1200 = 20s
s = 60m
