Since force is dp/dt, the force due to radiation pressure reflected off of a solar sail can be calculated as 2 times the radiative momentum striking the sail per second. in the vicinity of earth's orbit around the sun, the energy intensity of sunlight is about 1300 w/m2. what is the approximate magnitude of the pressure on the sail? (for comparison, atmospheric pressure is about 105 n/m2.)

The velocity of a curling stone is due east. what will be the direction of the momentum of the curling stone as it moves?

Suppose a wire with a current is pushed upward by a magnetic field. how would the wire move if the direction of the current reversed? explain your answer.

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
