Along thin rod of mass m and length l is situated along the y axis with one end at the origin. a small spherical mass m1 is placed at the location p, which is at a distance d from the origin.

if l = 2.00 ? 104 m, d = 18.0 ? 104 m, m = 14.0 ? 106 kg, and m1 = 8.00 ? 106 kg, what is the value of this potential energy?

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) determine the magnitude and direction of projectile velocity at t= 1.3s b) determine the magnitude and direction of projectile acceleration at t=1.3s

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
