A driver of a car travelling at 52 km h applies the brakes accelerates uniformly in the opposite direction. The car in 5 s. Another driver going at 3 kmh in another car apps his brakes slowly and stops in 10 s. On the same graph paper plot the speed versus time graphs for the two cars, which the two cars travelled farther after the brakes were applied?

How to calculate voltage drop in a series circuit

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
