In the second 30 mins, the speed should be 20 + 1.5 = 21.5 km/h
So S = 21.5 * 30/60 = 10.75 km
Answer:
Its not A..
Explanation:
I chose A - was incorrect
As per Newton's III law every action has equal and opposite reaction
So here we can say that
every body which apply force on other body must have a reaction force of same magnitude in opposite direction
So here if ball hits the ground by 50 N force then the ball must have a reaction force on itself with same magnitude and opposite direction
the magnitude of the force will be 50 N
and its direction is opposite to the force that ball apply on the floor
1. Because of gravity....
2. No you either feel still ( gravity) or is actually in movement....
please vote my answer branliest! Thanks
False
Energy in the form of motion is kinetic energy
Stored energy is called potential energy
