A block rests on an inclined as shown in figure, angle of the slope is θ. The Force F is applied so that the block just starts (barely) moving upward. Answer the following Question. A1 and A2 as well as F1 and F2 are the component of Force A and Force F.  Q PIC.png If, the Applied Force is 84 N, the slope is 300 and the mass of the block is 4 kg, what is the coefficient of static friction of the surface?

A system consists of three particles located as shown in below. The masses of the particles are m1 = m2 = 1.0 kg and m3 = 2.0 kg. cm pic.png The position vector of the center of mass is given by

A hockey puck having a mass of 0.30 kg slides on the frictionless, horizontal surface of an ice rink. Two hockey sticks strike thepuck simultaneously, exerting the forces on the puck shown in Figure below. The force F1 has a magnitude of 5.0 N, and the force S F2 has a magnitude of 8.0 N. HOCKY.png Magnitude of the pucks y- component of total acceleration is :

An elevator car (Fig. Below) has a mass of 1000 kg and is carrying passengers having 200 kg altogether. A constant friction force of 400 N retards its motion.  Find power delivered by the elevator if it is moving up with constant velocity of 10 m/s. qr.png

A hockey puck having a mass of 0.30 kg slides on the frictionless, horizontal surface of an ice rink. Two hockey sticks strike thepuck simultaneously, exerting the forces on the puck shown in Figure. The force F1 has a magnitude of 5.0 N, and the force S F2 has a magnitude of 8.0 N. HOCKY.png Magnitude of the pucks x- component of total acceleration is :

An 8.0-g bullet is shot into a 4.0-kg block, at rest on a frictionless horizontal surface (see the figure). The bullet remains lodged in the block. The block moves into an ideal massless spring and compresses it by 8.7 cm. The spring constant of the spring is 2400 N/m. qq.jpg What is the potential energy stored in the spring after the spring is compressed by 8.7 cm?
