Answer:
7.53 m
Explanation:
Force, F = 47 N
initial velocity, u = 0
Final kinetic energy, Kf = 354 J
Let the distance traveled by the student is s.
According to the work energy theorem,
Work done by all forces = Change in kinetic energy
Force x distance = final kinetic energy - initial kinetic energy
F x s = kf - ki
47 x s = 354
s = 7.53 m
