Question

After studying the motion of a ball rolling on a straight line as shown in figure:

Find its distance and displacement covered
1] when it goes from P to Q and then to R (i.e. P to Q to R ) and
2] finally comes back to P(i.e. P to P) (take P as reference point)​

Answer 1

Answer:

displacement =0

distance=p to q=10

q to r=2

and r to p again =8

10+2+8=20
