Physics 101- Introduction to Mechanics
|February 6- 2-D Motion|
Consider a bicyclist that is traveling at a constant
speed of 5m/s. During the observed time interval they ride along
a straight road, then make a right turn, continuing in their new direction
at 5m/s. Do they ever accelerate?
A car is moving at a constant speed travels
past a valley in the road, as shown. Which of the arrows shown most
closely approximates the direction of the carís acceleration at the instant
that is at the position shown?
What if the car is speeding up? Which
way does the acceleration vector point then?
