A 48 kg skier starts from rest at a height of H = 28 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless.
Could u give me a formula i need to start...
The only force acting on a 3.4 kg body as it moves along the positive x-axis has an x component Fx = - 6x N, where x is in meters. The velocity of the body at x = 3.0 m is 8.0 m/s.
a) What is the velocity of the body at x = 4.0 m? m/s
(b) At what positive value of x will the body have a...
there is another problem here is the link if u could help me with that i don't even know how to start https://www.physicsforums.com/showthread.php?p=2677818#post2677818
A block with a weight of 3.0 N is at rest on a horizontal surface. A 0.9 N upward force is applied to the block by means of attached vertical string.
(a) What is the magnitude of the force of the block on the horizontal surface?
While two forces act on it, a particle is to move at the constant velocity v = (3 m/s) - (4 m/s) . One of the forces is F1 = (4 N) + (- 7 N) . What is the other force?
i know the formula Fnet=ma and i can't use it to find mass in this case how can i find mass first so and i know that...
