acceleration is given as r= 0.65 m, t= 0.29 and i = -0.25 m/s, calculate the velocity and acceleration of the grip M. Also, calculate the radial and transverse forces F, and Fg, on the gripped part M which has a mass of 1.5 kg.

A block of wood of mass 20 kg is supported as shown in the diagram. If the string suspending the 10 kg mass and connected to the 20 kg mass is light and inextensible and the coefficient of friction, u between the mass and the plane is 0.3 neglecting friction in the pulley (i) Compute the acceleration of the block. (ii) Determine the tension in the rope. 20 kg 10 kg 30°

Find the rato of masses m1/m2

A box with mass m = 2.75 kg rests on the top of a table. The coefficient of static friction between the box and the table is μs = 0.71 and the coefficient of kinetic friction is μk = 0.34. Write an expression for Fm the minimum force required to produce movement of the box on the top of the table. Solve numerically for the magnitude of the force Fm in Newtons. Write an expression for a, the box's acceleration, after it begins moving. (Assume the minimum force, Fm, continues to be applied.) Solve numerically for the acceleration, a in m/s2.
