EXAMPLE 1: GOLF BALL STRUCK B A golf ball of mass 50 g is struck with a
club. The force exerted by the club on the
ball varies from zero, at the instant before
contact, up to some maximum value and
then back to zero when the ball leaves the
club. Assuming that thc ball travels 200 m
and the launch angle is 45°, estimate the
magnitude of the impulse caused by the
collision

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

Where do magnetic lines of force enter earth?

Aforce of 8,480 n is applied to a cart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?
