Chapter 3.8 & 6 Solutions P3.37. Prepare: We are asked to find period, speed and acceleration. Period and frequency are inverses according to Equation 3.26. To find speed we need to know the distance traveled
Speed (a scalar quantity) is the distance travelled every second.
SCALAR and VECTOR QUANTITIES The following are some of the quantities you will meet in the Intermediate Physics course: DISTANCE, DISPLACEMENT, SPEED, VELOCITY, TIME, FORCE. Quantities can be divided into
