A 12 kg object is pushed from rest to a final velocity of 10 m/s. The object travels 6 m. How much force was the object pushed with?
Options
A
600 N
B
100 N
C
200 N
D
1200 N
Answer & Analysis
Answer
B
Analysis
To find the force that was applied to the
object, we can use the work-energy theorem, which states that the work done on
an object is equal to the change in its kinetic energy:
Since the object starts from rest,
, and the final kinetic energy is given by:
Calculate the final kinetic energy
