Question: A mass of 1200 kg is moving with a speed of 17.5 m/s as it starts up an inclined surface. The surface is inclined 5 degrees above the horizontal and there is friction between the mass and the surface (µ= 0.290).
Part A: What is the distance up the incline does the mass move before it stops?
I want help to find the distance up the incline does the mass move before it stops.
Suppose that you'd like to find out if a distant star is moving relative to the earth. The star is much too far away to detect any change in its brightness as it moves toward or away from the earth. Instead we can use the Doppler effect to determi..
What percentage of the input energy needed to pump the water up to the top tank could you recover from the turbine as the water ran back to the bottom tank, two 15,000 litre water tanks and put one on a frame 3m higher than the other,

The isotope of lithium used in a hydrogen bomb is Li-6, whose nucleus contains 3 protons and 3 neutrons. When a Li-6 nucleus absorbs a neutron, a nucleus of the heaviest hydrogen isotope, tritium (H-3), is produced.
A 18800 kg helicopter lifts a 4700 kg truck with an upward acceleration of 1.5 m/s2. Compute (a) the net upward force on the helicopter blades from the air and (b) the tension in the cable among the helicopter and truck.
