QUESTION 3 Problem A moving electron has a Kinetic Energy Kq. After a net amount of work is done on it, the electron is moving one- quarter as fast in the opposite direction. What is the work done W in terms of Kq? Solution To solve for the work done, first we must determine what is the final kinetic energy of the electron. By concept, we know that K1=(1/2)mv²1 K2=(1/2)mv2 But it was mentioned that: v2=( V1 so, K2 in terms of v1 is K2=( )mv²1 Substituting the expression for K1 results to K2=( )K1 Since work done is W=AK=K -K Evaluating results to W=( )K1

A weight lifter lifts a 380-N set of weights from ground level to a position over his head, a vertical distance of 2.40 m. How much work does the weight lifter do, assuming he moves the weights at constant speed? My answer was 855 This was my feedback Please fix this Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J

3. DETAILS n mq MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.95 m off the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to calculate the average force upward on…

A net external force must act on the satellite to make it change to a circular orbit that has a radius of 8.61 × 106 m. What work must the net external force do? Note that the work determined here is not the work Wift done by the satellite's engines to change the orbit. Instead, the work W is W = Wift + Wgravitational, where Wgravitational is the work done by the gravitational force.
