Q. Team A is pulling on a rope attached to a 138.0 kg anvil. They are pulling in the direction of 32 degrees N of E with the force of 348 N. Team B is pulling on a rope attached to the same anvil with the same force but in direction of 32 degrees S of E. What is the initial acceleration of the anvil?
Q. Children in the tree house lift a small dog in a basket 4.70m up to their house. If it takes 201 J of work to do this, what is that combined mass of dog and basket?
how long does it take to reach the new equilibrium position.
Consider the 642 N weights held by two cables shown. The left-hand cable had tension T2 and makes an angle of thelta2 with ceiling. The right-hand cable had tension 460 N and makes an angle of 47 degrees with the ceiling.
suppose that no heat is lost to the surroundings, what is the situation when termal equilibrium is reached.
Assume a rocketship in deep space moves with constant acceleration equal to 9.8 m/s2, which gives the illusion of normal gravity during the flight. Estimate the time required by a rocketship to attain the speed of light and the distance travelled t..

A vertical scale on a spring balance reads from 0 to 175. The scale has a length of 12 from the 0 to 175 reading. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.8.
A 35.0-g bullet moving at 475 m/s strikes a 3.2-kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 225 m/s. How fast is the bag moving while the bullet exits.
A flight attendant pulls her 64 N flight bag a distance of 370 m along a level airport floor at a constant velocity. The force she exerts is 45 N at an angle of 51° above the horizontal.
At one instant a bicyclist is 40m due east of a park's flagpole, going due south with a speed of 10m/s. Then 30.0s later, the cyclist is 40m due north of the flagpole.
