Question

Two bodies starts moving from same point along a straight line with velocities v1 =6m per sec and v2=10 m per sec simultaneously after what time their separation becomes 40m

Answer 1

The first particle is moved with constant velocity u and the second worth consider the position of a body.

This usually taking place with moving axis along with time and consider by giving X=(t-4+6)m.

Two cars start off race with velocities and simultaneously travel at time separation of 6m/s as measured.
