A pickup truck carries cans of paint (each of mass m) in the back bed. The coefficient of static friction between the cans and the bed of the truck is 0.54. There is no back gate to the truck. When the truck accelerates from rest, the paint cans do not slip out of the bed of the truck. (a) If the truck travels in the positive x-direction, in what direction does the static friction force act? (b) What is the maximum allowable acceleration the truck can have without losing paint cans out of the back, in terms of the variables given in the problem (and g if relevant)? (c) How long must the driver take to accelerate to 55 mph in order to avoid losing paint cans out of the truck's back?

Please don't provide handwritten solution ...

Responses should be as simple as possible, and in typed form, with all applicable units, following a clear and straightforward logical structure. NO hand-drawn explanations are allowed. Ensure the appropriate use of significant figures, and when applicable, employ the "variable space" framework for providing answers.

Back when I was a kid, I loved to play with my Hot Wheels. Hot Wheels are miniature metal cars that race down lengths of flexible track. The track comes in segments that can be connected together. One thing you can do is make the cars Loop the Loop, as shown in the figure above. Starting at a height, h, the cars race down the track, traverse a circular loop of radius, R, without falling down at the top of the loop, and then continue racing along a section of level track. If the loop is 9 inches in diameter, what is the minimum height, h, from which the cars can start and still loop the loop without falling down at the top? Neglect friction and air resistance.
