Question

an object moves along a straight line with an acceleration of 2 metre per second square if its interior speed is 10 M per second what will be its speed for second letter​

Answer 1

Proof of Kepler's 2nd Law

Kepler's Second Law. We shall consider Kepler's Second Law (that the planet sweeps out equal areas in equal times) first, because it has a simple physical interpretation. so the rate of sweeping out of area is proportional to the angular momentum, and equal to L/2m.
