Three 0.3 kg billiard balls are placed on a table at the corners of a right triangle as shown in the Figure. Find the net gravitational force on the ball designated as m1 due to the forces exerted on it by the other balls.

Step 1
The formula for gravitational force is: F = G * (m1 * m2) / r^2 where: - F is the gravitational force, - G is the gravitational constant (6.67 × 10^(-11) N·m/kg), - m1 and m2 are the masses of the two objects (in this case, the billiard balls), and - r is the Show more…

Three identical 50 kg balls are held at the corners of an equilateral triangle, 30 cm on each side. If one of the balls is released, what is the magnitude of its initial acceleration if the only forces acting on it are the gravitational forces due to the other two masses? (G=6.67 x 10-11 N . m2/kg2)

A rack of seven spherical bowling balls (each $8.00 \mathrm{~kg}$, radius of $11.0$ $\mathrm{cm}$ ) is positioned along a line $1.00 \mathrm{~m}$ from a point $P$, as shown in $\underline{\text { Figure } 10-}$ 23. Determine the gravitational force the bowling balls exert on a ping-pong ball of mass $2.70$ g centered at point $P$. Example $10-4$
A billiard ball strikes and rebounds from the cushion of a pool table perpendicularly. The mass of the ball is $0.38 k g$. The ball approaches the cushion with a velocity of $+2.1 \mathrm{m} / \mathrm{s}$ and rebounds with a velocity of $-2.0 \mathrm{m} / \mathrm{s}$ . The ball remains in contact with the cushion for a time of $3.3 \times 10^{-3} \mathrm{s}$ What is the average net force (magnitude and direction) exerted on the ball by the cushion?
