Dec 05, 2012 · Draw a free-body-diagram. You'll find that the component of the gravitational force that acts perpendicular to the plane (equal in magnitude to the normal force) has a magnitude of mgcos(65) (use trig). Since the frictional force = the coefficient times the normal force, you have . Ff = o*mgcos65. Use Newton's Second Law = F=ma = o*mgcos65 = ma •The mass, m, is a scalar quantity. •1 N = (1 kg)(1 m.s-2) = 1 kg.m.s-2 Newton’s definition: ”The rate at which a body’s momentum changes is equal to the net force acting on the body” The more familiar version: ! F net =m! a Note that Newton’s 2nd law includes the 1st law as a special case (F = 0). 14.

A 4 kg mass is released on a frictionless slope which is at an angle of 30 o to the horizontal. Gravity causes the mass to accelerate down the slope. But the force of gravity, or W, acts vertically downwards.

When you have a block of ice (read: frictionless) moving down a ramp, it’s being acted on by forces, which means that it’s accelerated. How fast is it being accelerated? When you know that F = ma, you can solve for the acceleration. After you solve for the force along the ramp, you can get the acceleration (a = F / m) along the ramp.
