- a block of mass m is held stationary on a ramp by the frictional force on it from the ramp. A force , directed up the ramp, is then applied to the block and gradually increased in magnitude from zero. During the increase, what happens to the direction and magnitude of the frictional force on the block?arrow_forwardProblem 4: A crate of mass m is initially at rest at the highest point of an inclined plane, which has a height of 4.3 m and has an angle of 0 = 22° with respect to the horizontal.

- A nucleus that captures a stray neutron must bring the neutron to a stop within the diameter of the nucleus by means of the strong force. That force, which "glues" the nucleus together, is approximately zero outside the nucleus. Suppose that a stray neutron with an initial speed of 1.1 × 10' m/s is just barely captured by a nucleus with diameter d = 1.5 × 1014 m. Assuming that the strong force on the neutron is constant, find the magnitude of that force. The neutron's mass is 1.67 x 1027 kg. %3D Number Unitsarrow_forwardA man pushing a crate of mass m = 92.0 kg at a speed of v = 0.880 m/s encounters a rough horizontal surface of length { = 0.65 m as in the figure below.
