You are pulling your sister on a sled to the top of a 18.0 m high, frictionless hill with a 10.0° incline. Your sister and the sled have a total mass of 50.0 kg. You pull the sled, starting from rest, with a constant force of 127 N at an angle of 45...
Answer:
The component of force parallel to the slope (Fc)= 127 x cos45* = 127 x 0.71 = 89.80 Newton The length...

please help me asap! thanks:) A child and sled with a combined mass of 46.0 kg slide down a frictionless hill that is 10.4 m high at an angle of 26 ◦ from horizontal. The acceleration of gravity is 9.81 m/s2. If the sled starts from rest, what is its...
Answer:
if using kinematics: acceleration down the hill is g sin(theta) = 9.81m/s/s x sin 26 = 4.30m/s/s the...
