Answer #1

The whole ramp problem is depicted in the following picture: Let the mass of the cart is m and is the angle of inclination. The weight of the cart is acting downward (neither perpendicular to ramp surface not parallel), hence we divide it into two components along ramp surface perpendicular to ramp surface obviously as reaction force or normal force due to weight again the component of applied force along normal direction is FCos90 net force on the cart is The weight of the cart is acting downward

An object with a mass of 10.0 kg is falling under the effect of gravity near the earth's surface with negligible air resistance. There is a force of 55 N pushing it to the left (you can pretend that this force is due to wind if that helps). What is the magnitude and direction of the total force felt by the object? Note: if the magnitude is greater than 140 N then you have done this problem wrong and you...

You are a medical consultant to a health technology company evaluating an inexpensive traction system for exerting a predictable force at the location of a patient’s leg injury. The device consists of a foot-strap connected to a weight by a rope that goes over a pulley. You are worried that the force exerted on the injury will change when the angle of the leg changes. As a first step in understanding the situation, you decide to model the portion of...

Two masses are connected to one another with a massless rope that passes over a massless and frictionless pulley as shown in the figure below. When the two mass system is released from rest, the hanging mass m2 = 31.5 kg accelerates upward at a rate of 2.3 m/s2. The coefficient of kinetic friction between m1 and the incline is 0.08, and the angle of inclination of the ramp is 57 degrees. For the entirety of this problem, air resistance...
