Two forces are acting on a 0.150-kg hockey puck as it slides along the ice. The first force has a magnitude of 0.405 N and points 35.0° north of east. The second force has a magnitude of 0.605 N and points 55.0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck\'s acceleration? Enter the direction as an angle measured in degrees counterclockwise from due east. A) Magnitude of acceleration = _ m/s2 B) Direction of acceleration = ____ degrees

Half of the person’s weight is supported by the crutches,the other half by the vertical forces exerted by the ground on his feet. Assuming he is atrest and the force exerted bythe ground on the crutchesacts along the crutches, determine(a) the smallest possiblecoefficient of friction betweencrutches and ground and(b) the magnitude of the compressionforce supported byeach crutch.

Consider the figure below, which has two objects of mass mi 3 kg connected by a taut rope. m2 Fp m2 Frictionless Finger Ms, Mk = The ramp is at an angle of 0 40° and has the peculiar property that it is frictionless along the tilted surface, but not along its vertical surface.
