Chapter 5, Problem 11P
Review. An electron of mass 9. 11 × 10−31 kg has an initial speed of 3.00 × 105 m/s. It travels in a straight line, and its speed increases to 7.00 × 105 m/s in a distance of 5.00 cm. Assuming its acceleration is constant, (a) determine the magnitude of the force exerted on the electron and (b) compare this force with the weight of the electron, which we ignored.

An electron is a subatomic particle (m = 9.11 x 10-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.81 x 105 m/s to a final velocity of 2.69 x 106 m/s while traveling a distance of 0.0663 m. The electron's acceleration is due to two electric forces parallel to the x axis: F1−→F1→ = 9.79 x 10-17 N, and F2−→F2→, which points in the -x direction. Find the magnitudes of (a) the net force acting on the electron and (b) the electric force F2−→ .
In the figure, a slab of mass m1 = 40 kg rests on a frictionless floor, and a block of mass m2 = 10 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force F→ of magnitude 104 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?
According to a simplified model of a mammalian heart, at each pulse approximately 20 g of blood is accelerated from 0.25 m/s to 0.35 m/s during a period of 0.10 s. What is the magnitude of the force exerted by the heart muscle?
