calculate the largest asteroid that an astronaut could escape from by jumping.

This problem is difficult because it involves so many concepts in one problem. It is necessary for the emphasis to be on clear and logical discourse for each step of the solution. Each step must be clearly explained. The problem is as follows. Calculate the largest asteroid that an astronaut could escape from by jumping vertical ...continues

momentum 1

1. A pitcher claims he can throw a 0.145 kg baseball with as much momentum as a speeding bullet. Assume that a 3.00 g bullet moves at a speed of 1.50 x 10^3 m/s. a. What must the baseball's speed be if the pitcher's claim is valid? B. Which has greater kinetic energy, the ball or the bullet? 2. What is the relations ...continues

What is the gravitational force between two trucks, each with a mass of 2.0 x 10^4 kg, that are 2.0 m apart? 3. The gravitational ...continues

dopplers effect

Two automobiles are equipped with the same single frequency horn. When one is at rest and the other is moving toward an observer at 15.9m/s, a beat frequency of 5.60Hz is heard. What is the frequency the horns emit? Assume T= 20 degrees celsuis

frequency

The frequency of a steam train whistle as it approaches you is 538Hz. After it passes you, its frequency is measured as 509 Hz. how fast the train moving ( assume constant velocity)? Assume the speed of sound is 343m/s.

angular acceleration

In a pulley system, the time of descent of a 100 gram mass is found to be 35 seconds. The vertical distance is given as 120 cms. The radius of the pulley( in the form of a disc) is 5 cms. Mass of the pulley is unknown. Determine (a) angular acceleration of the pulley (b) number of revolutions it makes during this time (c) To ...continues

Dynamics of rotational motion

Atwoods Machine Two blocks, A and B are attached to each end of a cord attached to a pulley C. Block A hangs slightly higher than Block B. Find the linear accelerations of block A and B, and the angular acceleration of the wheel C and the tension in each side of the cord if there is no slipping between the cord and the surf ...continues

Dynamics

A uniform, solid cylinder with mass M and radius 2R rests on a horizontal tabletop. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about the axle. The string runs over a disk shaped pulley with mass M and radis R that is mounted on a frictionless axle th ...continues
