PHYSICS HOMEWORK #53

An object, which has a mass of 6. What are the magnitude and direction of the centripetal force acting on this car when at the location shown? A rifle bullet, which has a mass of The force F is generally supplied by a screw which is turned by a lug wrench. Two masses are connected together by a string which is then hung over a pulley which is mounted on the ceiling as shown in the diagram to the left. A force F is applied so as to push the crate up this incline at a constant speed.

A ball is thrown downward from the top of a building meters tall with an initial speed of From your graph determine the average velocity of this object as a function of time. A car, which has a mass of kg. According to the tachometer in a car the engine is rotating at RPM [revolutions per minute]. Where along the length of the bridge could a single upward force be applied so as to lift the bridge without tilting?

A car is at rest on a horizontal surface. The accelerator is applied and the car accelerates at 3. As a result the sled accelerates to the right at a rate of 3. What will be the direction a and magnitude of the total momentum of these two masses physixs the collision?

What will be the magnitude of the gravitational force component opposing the motion of the sled up the incline? Lorentz force wikipedialookup.

How far are you from your starting point? The planet Mars orbits the sun at a distance of 2.

However, the wind is blowing due South with a velocity of How far will your car move from the time you apply the brakes until the car stops? Through what angle will this engine rotate each minute? How much will the spring be compressed just as the ball comes to rest against the spring?

What is the kinetic energy of this car? A satellite, which has a mass of kg. What will be the magnitude of the tension T in the rope? A satellite is to orbit the Earth so that its period is 2. How much work will be done in lifting this physic onto the table? This boat then reverses direction and returns to the point of origin.
