If a force of 50 N is applied to a box of mass 2 kg for 2 seconds, what is the work done on the box?
Answer: 2500 J
Explanation
Work done (W) is given by:
W = F * d
where F is the force applied and d is the displacement.
Since the mass of the box is 2 kg and a force of 50 N is applied for 2 seconds, we can calculate the acceleration (a) using:
F = m * a
a = F / m
= 50 / 2
= 25 m/s²
The displacement (d) can be calculated using:
d = (1/2) * a * t²
where t is the time.
d = (1/2) * 25 * (2)²
= 50 m
Now, we can calculate the work done:
W = F * d
= 50 * 50
= 2500 J
