Answer:
50,000 joules
50kJoules
Step-by-step explanation:
F = m * a
here, m = 100kg. a = 10m/s^2
F = 100 * 10
= 1000 Newtons
Here, d= 50m. F = 1000newtons
W = F * d
= 1000 * 50
= 50,000 joules
= 50 kilo joules
20 joule is your answer
here
mass m =100kg
distance d=50m
acceleration due to gravity a =10m/s²
work =force×displacement
= ma/d=100×10/50=20joule
