Question 2 A small car is driving in a horizontal circle on the inside surface of a cone as shown. The car has mass M and is moving with a constant speed of V. Assume there is no friction acting on the car. The horizontal circle is located at a height H above the point of the cone as shown. The angle between the centre of the cone and the side (the half angle) is ? as shown. a) Draw...

1) A cart for hauling ore out of a gold mine has a mass of 447 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.63∘ incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 436 N force for a distance of 115 m by means of a rope that is parallel to the...

1. Questions 1 through 7: Four charges are placed at the corners of a square 5 cm on a side. Two of the charges - one at the origin (x,y) = (0,0) cm and the one on the y-axis at (0,5) cm have positive charges of 10-9 Coulombs. The other two charges one on the x-axis at (5,0) cm and the other at (x,y)= (5,5) cm have negative...
