A hockey puck has a mass of 0.113 kg and is at rest. A hockey player makes a shot, exerting a constant force of 28.0 N on the puck for 0.16 s. With what speed does it head toward the goal
find the force exerted by the rope on the bucket. A metallic object is given the negative charge by the process of induction. What happens to object's mass.
Calculate the kinetic energies of two uniform solid cylinders, each rotating about its central axis. They have the same mass, 2.75 kg
The former move along the surface of the earth much like the ripples in the surface of a pond, while the other type propagate through the whole earth forming a hemisphere around the point of origin of the quark assuming that it occurred close to t..

Two cubes make from the same material. The radiant energy per second emitted by the small cube (1L ) is 0.675j/s. What is the energy emitted per second by the large cube (2L)
Two thin rods of length L lie along the x-axis, one between x=a/2 and x=a/2+L and the other between x= - a/2 and x= - a/2 - L. Each rod has positive charge Q distributed uniformly along its length.
A hotel elevator ascends 160m with a maximum speed of 4.20 m/s. Its acceleration and deceleration both have a magnitude of 1.0 m/s2. How long does it take to make the complete trip from bottom to top.
This problem introduces the concept of tension. The instance is a rope, oriented vertically, that is being pulled from both ends. Let and (with u for up and d for down) represent the magnitude of the forces acting on the top and bottom of the rope..
