A 0.52 kg box of macaroni is held in place at the front of a 3.33 kg shopping cart only by the force of static friction as the shopping cart accelerates. Determine the minimum acceleration, in m/s 2 , that the shopping cart must have if the box is to be kept from falling if the coefficient of static friction between the box and cart is 0.52.

A block of mass m is placed against the vertical front of a cart
of mass M as shown in the figure. (Figure 1)
Assume that the cart is free to roll without friction and that
the coefficient of static friction between the block and the cart
is μs. Derive an expression for the minimum
horizontal force that must be applied to the block in order to keep
it from falling to the ground.

A box (350 kg) sits inside the trailer of a semitruck traveling at a speed of 15 m/s (~ 33 mph). Suddenly, a car in front of the truck stops in the road. The driver of the truck hits the brakes to bring the truck to a stop. Assume that the coefficient of static friction µs = 0.7 between the box and the floor of the trailer. Assume g = 10 m/s2. When the truck is slowing down, what is...

In an elevator, a loose .400kg square ceiling tile is only held in place by the friction force from the four sorrounding tiles (the coefficient of static friction between the tiles is .500). If the normal force from each tile is 2.00 N what acceleration of the elevator will cause the tile to fall on an unsuspecting physics professors head? In what direction must the elevator be accelearting for this to happen?
