*** A force of 75N is applied to a nutcracker to crack open a walnut. If the MA of the nutcracker is 5, what is the force the nutcracker applies to the walnut?

Blocks mị and m2 are connected by a rope as shown in the figure. There is friction between mi and the wall, where the coefficient of static friction is ls. There is no friction between m2 and the ramp. An unknown force P is applied to mį so that mị is about to slip down the wall and m2 is about to move down the ramp. If the magnitude of the normal force on m2 is n2, find m2, the magnitude of P, the magnitude of the friction force on m1, and the magnitude of the tension force in the rope. The knowns are ls, n2, m1, g, and 0. P = ? Hs rope wall no friction m2 = ? ramp

A string has a tension T = 5.3 Newtons and connects the two blocks of m1 =3.0 kg and m2 =11.7 kg. Find the value of force F in Newtons assuming the friction is negligible. (only numbers in the box)
