Question

starting from rest at the top of an inclined plane a body reaches the bottom of the inclined plane. in for second in what time does the body cover one -fourth the distance starting from rest at the top
A. 1second
B. 2second
C. 3second
D. 4second​

Answer 1

Answer:

x=1/2at

2

{Since u=0}

Putting t=4 seconds, we get:

x=8a

Now, x/4=2a,

To find out the time taken to travel a distance of x/4 on the same plane,

2a=1/2at

2

⟹t

2

=4

⟹t=2s.
