Question

A frog hops along a straight line path of 7cm from path to point b in 10 seconds and then turns around and hopes 4cm back to c in another 5 seconds .calculate the frogs average speed and average velocity in hopping (a)from a to b(b)from a to c

Answer 1

Answer:

Let distance from A to C=x m.

Let distance from B to C=y m.

Average speed=m/s(x+y)/(15)=(x+y)/15 m/s

Displacement=x m along A to C

Average Velocity=x/15 m/s
