10- A stopwatch is used to time the motion of a car. At time t=12.0 s the car is at x=50.0 m. At t=15.0 s the car is at x=5.00 m. What are the
car's (a) average velocity and (b) average speed?

What is the magnitude of the resultant vector round your answer to the nearest tenth

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
