(b) change in velocity and time - Answer The 2 measurements necessary for calculating
average acceleration are
(a)instantaneous velocity & time (b) change in velocity and time (c) distance and speed (d)
velocity and distance
(a) 0 - Answer What is the acceleration of a car that maintains a constant velocity of 100
km/hr for 10 secs?
(a) 0 (b) 10 km/hr(s) (c) 10 m/hr(s) (d) 1000 km/hr(s)
(c) 100 m/s - Answer Ten seconds after starting from rest, an object falling freely downward on
Earth will have a speed of about
(a) 10 m/s (b) 50 m/s (c) 100 m/s (d) more than 100 m/s
(a) 10 km/hr - Answer The average speed of a horse that gallops a distance of 10 km/hr in a
time of 1 hour is
(a) 10 km/hr (b) 20 km/hr (c) 30 km/hr (d) more than 30 km/hr
(e) Your direction is constantly changing - Answer Suppose you are in a car going due east on a
straight highway at a constant speed of 30 mph. Which of the following is NOT true?
(a) You and the car's distance is constantly changing
(b) Your speed is constant
(c) Your velocity is constant
(d) Your acceleration is 0 m/s/s
(e) Your direction is constantly changing
(b) 20 m/s - Answer If an object falling freely downward was somehow equipped with a
speedometer on a planet where the acceleration due to gravity is 20 m/s/s, then its speed
reading would increase each second by
(a) 10 m/s (b) 20 m/s (c) 30 m/s (d) 40 m/s (e) Depends on initial speed
