Acceleration is defined as the rate of change for which characteristic?

the force of gravity causes it to accelerate.

its mass doubles for every second it falls.

it changes direction every 9.8 meters.

it falls at a constant velocity.

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

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.
