A van of mass 1600 kg was moving at a velocity of 16 m/s when it was involved in a head on collision with a wall. Assuming that the van came to stop after the collision,
a. find the change in momentum of the van
b. if the van took 0.2 s to stop, what is the force that acted on each driver.

Identify the forces that contribute to the centripetal force on the object in each of the following examples: a. a bicyclist moving around a flat, circular track b. a bicycle moving around a flat, circular track c. a racecar turning a corner on a steeply banked curve

Compare the patterns of the two waves shown in the image. which statement is true about these waves?

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
