Suppose you place a10kg block on a 300 inclined plane. the block is allowed to slide to the ground, a horizontal distance ofdmeters and a vertical distance ofhmeters. if coefficient of kinetic friction is 0.45, calculate the magnitude of the kinetic and static friction. the plane is a right triangle. the 30 degrees is on the bottom and the 10 kg block is on the top of the hypotenouse.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
