Answer:
The answer is 4200 J.
Explanation:
The formula of work done is, W = F×D where F is the force of an object and D is the distance. Then you just substitute the values into the equation :
W = F×D
F = 42N
D = 100m
W = 42 × 100
= 4200 J

Explanation:
Distance = rate × time
1 m = (2.99792×10⁸ m/s) t
t = 3.33565×10⁻⁹ s
