A 65 N box is winged by a rope at a constant acceleration. Said box is displaced at a distance d = 3600 cm in a time t = 2.4 s from a point at rest. Determine the tension developed in the cable. The coefficient of kinetic friction between the box and the plane is ?? = ?. ??.
Two masses are connected by a rigid link as shown in Fig. Q3. The masses are resting on
an inclined plane. The masses are then released. Considering the coefficient of kinetic
friction between the inclined plane and the masses A and B are 0.1 and 0.2 respectively.
3.
Compute by using Newton's second law
a) The acceleration of both masses.
b) The force in the rigid link and specify whether it is in tension or compression.

Find the tension in each wire.Parrow_forwardA force F acts to the right on a 6.4 kg block. A 3.43 kg block is stacked on top of the 6.4 kg block and can slide on it with a coefficient of 1. 40.72541 2. 22.0506 friction of u1 =0.2 between the blocks. Both pulleys are massless and frictionless. The string is also massless. Note the axle of the upper pulley is free to move so it will accelerate to the left as the 6.4 kg block accelerates to the right. Think carefully about the magnitude of that axle's acceleration.
