A 1,140-kg car and a 12,600-kg truck approach each other from opposite directions. The truck is traveling at [01] km/hr. a. At what speed (m/s) would the car have the same momentum as the truck? b. The car and truck in (a) have a head-on collision and then stick together. What is their final common velocity (m/s)? (Assume the car is going in the positive direction.) c. What is the car’s change in momentum (kg m/s) in (b)? d. At what speed (m/s) would the same car have the same kinetic energy as the truck? e. The car and truck in (d) have a head-on collision and then stick together. What is their final common velocity (m/s)? (Assume the car is going in the positive direction.) f. What is the car’s change in momentum (kg m/s) in (e)?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
