Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holly Compton designed a speed bump (called the "Holly hump") and had it Installed. Suppose a 1800-kg car passes over a hump In a roadway that follows the arc of a cirde of radlus 20.0 m as in the figure below. (a) If the car travels at 29.4 km/h what force does the road exert on the car as the car passes the highest point of the hump? magnitude direction (b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point? km/h

Early test flights for the space shuttle used a "glider" (mass of 900 kg including pilot). After a horizontal launch at 460 km/h at a height of 3600 m, the glider eventually landed at a speed of 200 km/h. What was the average force of air resistance exerted on it if it came in at a constant glide angle of 10degrees to the Earth's surface?

A 20-Mg train is traveling at a speed of 50 m/s. But the driver noticed that the bridge300-m ahead is missing. At once, he pulls the break, thus applying a frictionalresistance of Ff = 1000 N. At the same time Super Botting pushes back the train witha force of Fs = [(123)d + 100] N, where d is the distance that the train travels before stopping.Determine the stopping distance d, and mention whether or not Superbotting wouldbe able to save the train.
A little toy car is powered by a CO2 cartridge that produces a thrust force according to the following function: Fthrust(t) = 6.0N e-0.2t. The car also has a friction coefficient of 0.05 due to the wheels and bearings. If the car's mass is 1.2kg, and the car travels in the +x direction, what will it's acceleration function look like as a function of time? If it starts from rest, what will vx(t) be? How fast will the car be going after 3.0s? What maximum speed will be reached by the car?
