The daily travel speed of a driver on a highway segment (X) has mean 58 mph and coefficient of variation 0.42. The speed limit at this highway segment is 75 mph. Assuming that the probability density function of X is lognormal: a. What is the probability that the driver violates the speed limit on any given day? b. What is the probability that the driver exceeds the speed limit less than 3 times over a month? c. There is a...
A projectile is launched horizontally at 32.4 m/s from the roof of a building 35m tall and experiences negligible air resistance. [A] Determine the time necessary for the projectile to reach the ground below. [B] Determine the distance from the base of the building that the projectile lands. (Range) [C] Using the horizontal and vertical components of the velocity just before the projectile reaches the ground (Vx and Vy). And determine the final velocity of the projectile (Vf).

The driver of a 1.19 103 kg car traveling on the interstate at 35.0 m/s (nearly 80.0 mph) slams on his brakes to avoid hitting a second vehicle in front of him, which had come to rest because of congestion ahead. After the brakes are applied, a constant kinetic friction force of magnitude 7.96 103 N acts on the car. Ignore air resistance. (a) At what minimum distance should the brakes be applied to avoid a collision with the other...
