jerk What is the slope of an acceleration-time graph?
t/f - . Two siblings leave their house and walk to the same school taking different routes. One of
the routes is
t farther, but the siblings take the same time to reach the school. It can be said that the two
siblings have the
same average velocity but different average speeds.
t/f - A car drives with constant speed around a corner. If it enters the corner travelling west
f, south-east and leaves travelling
south, its acceleration through the turn is directed south-west.
t t/f - If air resistance is negligible, the acceleration of all projectiles is exactly the same.
t/f - To achieve maximum range across a horizontal surface, the angle at which a projectile

A jogger is running at 4.2 m/s when she begins to accelerate uniformly. If she runs a distance
of 14 m in the
next 3.0 s, what is her new speed?
d a. 17 m/s
b. 14 m/s
c. 7.7 m/s
d. 5.1 m/s
e. 4.9 m/s
12. What distance does an object travel during a period of uniform acceleration (a = 2.5 m/s2)
when its speed
changes from 35 m/s to 45 m/s?
c a. 6.5 × 10^2 m
b. 3.2 × 10^2m
c. 1.6 × 1^2 m
d. 32 m
