if a coin and a piece of paper are dropped simultaneously from the same height which of two will touch the ground first? what will happen if they are dropped together in vacuum

A snail moves 40 cm in 20 seconds. How fast did it move?

A mass m = 14 kg is pulled along a horizontal floor with NO friction for a distance d = 5.7 m. Then the mass is pulled up an incline that makes an angle θ = 34° with the horizontal and has a coefficient of kinetic friction μk = 0.48.

The modern atomic model may seem strange when compared to earlier atomic models because it describes

Consider the following controls in an automobile in motion : gas pedal, brake, steering wheel. what are the controls in this list that cause an acceleration of the car?

3/129 A 175-lb pole vaulter carrying a uniform 16-ft, 10-lb pole approaches the jump with a velocity v and manages to barely clear the bar set at a height of 18 ft. As he clears the bar, his velocity and that of the pole are essentially zero.

A few years ago, Serena Williams dived to hit a tennis ball right after it bounced off the ground. The ball bounced on the ground 10.3 m from the net, and after Serena hit the ball it flew over the 0.
