A 70 kg mans arm, including the hand, can be modeled as a 75 cm long uniform cylinder with a mass of 3.5 kg. In raising his both his arms, from hanging down to straight up, by how much does he raise h
A 2.4 kg otter starts from rest at the top of a
muddy incline 89.8 cm long and slides down
to the bottom in 0.40 s.
What net external force acts on the otter
along the incline?
Answer in units of N-Th
1. Place the object close to the metre ruler, if you cannt do this, you can use a pointer...WWhat is the pointer?? pictures...descriptions...anything ..please help! :D

a ride at an amusement park have magnets that shoot the ride from rest to 45m/s (about 100mi/h) in a time of 7.0s. the combined mass of the car and the riders is 5.5x10E3 kg. find the averag net force
A 50,000 kg locomotive is traveling at 50.0when its engine and brakes both fail. How far will the locomotive roll before it comes to a stop?
This is all I am given. The answer is supposed to be in met
A person runs up several flights of stairs and is exhausted when they get to the top. Later, they walk up the same stairs and do not feel as tired. Why is this? Does it take more work or energy to run
Consider an airplane that normally has an airspeed of 100-km/h in a 100-km/h crosswind blowing from west to east. Calculate its ground velocity when its nose is pointed north in the crosswind.

A car exits a freeway on a circularly-shaped ramp that is banked at an angle of q = 23.5°. The ramp has a radius of curvature R = 48.6 meters. The ramp is icy, so you can neglect the effects of fricti
the other routes have resistors-If you have a 2 lane, toll-road and a 12 lane, non toll-road without speed limit, parallel to it, will all traffic pass through it?-Thats called a short circuit.
Yes,
So the original problem reads:
A 450 kg mass is accelerated at 2.5 m/s² : a) what is the force causing this acceleration? b) how fast is the mass traveling at the end of 3.0 seconds? c) how much dis
On a banked race track, the smallest circular path on which cars can move has a radius of 116 m, while the largest has a radius of 174 m, as the drawing illustrates. The height of the outer wall is 15
How come there is more resistance in a circuit with a higher temperature because wouldnt the electrons have more energy to move faster?-Electrons are moved ( drift) under an electric field.

How much tension must a rope withstand if it is used to accelerate a 1053 kg car horizontally along a frictionless surface at 1.19 m/s2?
please show me how to get the answer, i have a terrible teacher
My group mates and I have a video project about inertia and we all showed examples about it. My example was pressing a piano key. I was thinking that our teacher might think I am talking about the sou
