A block of mass m is placed on an inclined plane (a ramp). If a constant force f is applied to the ramp so that it is accelerating horizontally at a proper rate, the block will remain at the same height.
5.13 In Fig. 5.3, a body A of mass m slides on plane inclined at angle θ1 to the horizontal and µ1 is the coefficent of friction between A and the plane. A is connected by a light string passing over a frictionless pulley to another body B, also of mass m, sliding on a frictionless plane inclined at angle θ2 to the horizontal. Which of
Let us the acceleration of the block of mass M be a and let it be towards right. Therefore, the block of mass m must go down with acceleration 2a. As both the blocks are in contact, it (block of mass m) will also have acceleration a towards right. Hence, it will experience two inertial forces as shown in the free body diagram given below. 13.A vertical force of 500 N acts on a 12 kg mass over a horizontal displacement of 2 m. The work done by the force is A) 25 J B) 50 J C) 86.67 J D) 14.4 J E) 35 J 14.A woman pushes a lawn mower with a force of F at an angle to the ground. If F = 20N and = 30°,
Oct 03, 2010 · Homework Statement A block of mass m accelerates with acceleration g up a frictionless plane that is inclined at an angle α above the horizontal. The force Fo that pushes the block is at an angle β above the horizontal. Find the force Fo. 1. mg(1 + sin β)/cos(α + β) 2. mg(1 + sin...
