Does the magnitude of the force exerted by your legs have to be greater than your weight in order to jump off the ground ? Explain a diagram will help you.

View Policies Current Attempt in Progress The velocity of a 6 kg particle is given by = (6t î+ 2t² ĵ) m/s, with time t in seconds. At the instant the net force on the particle has a magnitude of 38 N, what are the direction (relative to the positive direction of the x axis) of (a) the net force and (b) the particle's direction of travel? (a) Number Units (b) Number Units

Determine the resultant of the forces shown in Figure P6-13. Find the coordinates. ly 10 kN -X Z 25 KN 15 KN

A cannonball has just been shot out of a cannon aimed 45∘ above the horizontal rightward direction. Drag forces cannot be neglected.Which way does drag point? I thought it points opposite of the direction of the motion.

A) Write an expression for the component of net force, Fnetx, in the x-direction, in terms of the variables given in the problem statement.  Fnetx=   Part (c) Write an expression for the magnitude of the normal force, F, acting on the block, in terms of F2, g, and the other variables of the problem. assume that the surface it rests on is ridged     Part (d) Find the block's acceleration in the x-direction, ax, in meters per second squared.

A skater of mass m standing on ice throws a stone of mass M with speed v in a horizontal direction. Find the distance over which the skater will move in the opposite direction if the coefficient of kinetic friction between the skater and the ice is  ?k . (Use any variable or symbol stated above along with the following as necessary: g.)Δx =

Topic:  You find yourself trapped in the middle of a large frozen lake. Assume the ice has no friction. All you have on your is warm winter clothing and no way to call/signal for help. You can just barely see the shore in the distance. Use your physics knowledge of Newton's laws to help get you off the lake. Explain your reasoning.
