Q. The gondola ski lift at Keystone, Colorado, is 2700 m long. On average, the ski lift rises 12.9° above the horizontal. How high is the top of the ski lift relative to the base?
Block A in Figure is given an initial velocity of 6 m/s up the incline. Declare of a block on a inclined plane.
A proton moves perpendicular to a uniform magnetic field, B, at 1.6 multiplied by 107 m/s and experiences an acceleration of 1.8 multiplied by 1013 m/s2 in the positive x direction while its velocity is in the positive z direction. Find out the magni..
A 258-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.980, and the log has ..
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
