Ablock of mass m 5 kg slides with an initial speed vi = 5 m/s to the right toward a ramp of mass m = 20 kg. the ramp itself can also slide without friction on the surface and has a frictionless face that the block can slide upon. the block slides up the ramp so that its center of mass rises a maximum height h, then back down until it is separated from the ramp. let velocities to the left be indicated by a negative
(a) determine the speed vh of the block-ramp system at the instant the block reaches its maximum height on the ramp m/s
(b) determine the height h to which the block's center of mass rises meters
(c) determine the final velocities vf and vr of the block and ramp, respectively final velocity of the block final velocity of the ramp = xm/s x m/s

Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (assume the data set has a bell-shaped distribution.)

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
