Q1. A child is riding across a rough field on a sled. Together, she and the sled have a mass of 73 kg. The sled is being pulled by her brother at an angle of 16º with a force of 356 Newtons. What is her acceleration if the coefficient of kinetic friction is 0.13?

Q2. Three identical masses of 610 each are placed on the x axis. One mass is at x1= -110, one is at the origin, and one is at x2= 430.

What is the magnitude of the net gravitational force on the mass at the origin because of the other two masses?

Take the gravitational constant to be G= 6.67×10-11.
