Question

Figure shows the variation of a force F acting on a particle along X axis. If the particle begins at rest at X=0 ,what is the particles coordinate when it again has zero speed?

Answer 1

Answer:mark me brainliest if it helps

Explanation:

Answer 2

Given that,

The variation of a force F acting on a particle along X axis.

If the particle begins at rest at X=0,

We need to calculate the particles coordinate when it again has zero speed

Using given graph,

When a force is applied on the particle then the particle can move.

When X=0, then the force is 10 N.

At rest,

The velocity is zero then there is no motion.

Again at the point,

When the applied force is zero then the particle does not move.

So, The velocity will be zero.

Hence, A point when the force is equal to zero.

That point is X=7.
