While merging in traffic, a driver increases her speed from 10 m/s to 20 m/s. What is the resulting change in the car's kinetic energy?

What are atoms of the same element with varying number of neutrons

In what direction does an applied force move an object

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
