Question 7 (1 point)
A student is investigating mass and acceleration. The student applies a force to two stationary boxes, as shown in the table.
Box
Force Applied to
Box (Newtons)
Acceleration
(meters/second2)
1 20 5
2 30 5
The student claims that Box 1 must have a smaller mass than Box 2. Which argument best supports the student's claim?
a
Lighter objects require less force than heavier objects to start moving but will accelerate at the same rate.
b
Lighter objects require greater force than heavier objects to start moving but will accelerate at the same rate.
c
Heavier objects require greater force than lighter objects to accelerate at the same rate.
d
Heavier objects require less force than lighter objects to accelerate at the same rate

Answer: c
Reason: From F = ma, for the same acceleration a, mass m = F/a. Box 2 has a larger force (30 N) for the same acceleration (5 m/s^2), so it must have a larger mass. Thus heavier objects require greater force than lighter ones to accelerate at the same rate.
