Question

The position(p) vs time(t) and velocity(v) vs time(t) graph of an object of mass 10kg is shown in 4 different situations. Find the net external force acting on the object in each case Pls answer this i need it

Answer 1

Answer:

(I) F = 0N

(ii)F = 0N

(iii)F = 100N

(iv)F = 0N

Explanation:

In first case position is changing linearly with time

hence, velocity is constant

that implies acceleration is 0

So force= 0

In second case position is constant hence velocity and acceleration are also constant

therefore force is zero

In third case velocity is changing linearly with time

so acceleration is constant which equals 10ms-1

So by calculation force is 100 N

In fourth case velocity is constant so acceleration is 0

therefore Force is 0

Thank you!!
