A machine operator produces the tension T in the control rod by applying the force P to the foot pedal. Determine the largest P if the magnitude of the pin reaction atBis limited to 1.8 kN. Neglect the mass of the mechanism.
An object, with mass 10 kg and speed 11 m/s relative to an observer, explodes into two pieces, one 4 times as massive as the other; the explosion takes place in deep space. The less massive piece stops relative to the observer. How much kinetic energ..
A vertical scale on a spring balance reads from 0 to 160 N. The scale has a length of 12.5cm from the 0 to 160 N reading. A fish hanging from the bottom of spring oscillates vertically at the frequency of 2.30 Hz. ignoring the mass of the spring, wha..
A 70kg man running at 1m/s jumps on a stationary 1kg skateboard and continues rolling in the direction he was running. Calculate his velocity as he rolls neglecting friction forces.
A tennis ball has a velocity of 26 m/s and a mass of 56.1 gram. After the ball hits a tennis racket, the velocity becomes twice that of the original speed and goes in the opposite direction. Compute the force between the racket and the ball
a 4.8 kg dog stands on an 19 kg flatboat and is 6.1 m from the shore. he walks 2.2 m on the boat toward shore and then
Asteroids are believed to be material that never collected into a planet. The asteroid Ceres has a period of 4.6 years. Assuming Ceres to be at the center of the planet if it had formed, how far would the planet be from the Sun?
The pendulum of a regulator clock consists of a mass of 120 g at the end of a (massless) wooden stick of length 44 cm. What is the total energy (kinetic plus potential) of this pendulum
While a hybrid car brakes to come to a stop at a traffic light, describe the energy transfer and materials used to transfer of this energy
find the speed of the test charge. find the distance the car travels during this time in m.
A positron is a particle with the same mass and magnitude charge as an electron, but a positron has a positive charge. how fast is the positron moving
conducting sphere x is initially uncharged. conducting sphere y has twice the diameter of sphere x and initially has
A positively charged particle of mass 6.2*10-8 kg is traveling north with a speed of 61 m/sand enters a 0.33 T uniform magneticfield. The particle moves through one-quarter of a circle in a time of 3.0*10-3 s, at which time it leaves the field hea..
