Answer:7350 joules
Explanation:
Mass(m)=10kg
Initial velocity(u)=2m/s
Final velocity(v)=3m/s
Time(t)=30s
Acceleration horizontally=a
Acceleration due to gravity(g)=9.8m/s^2
d=(u+v)/2 x t
d=(2+3)/2 x30
d=5/2 x 30
d=(5x30)/2
d=150/2
d=75
Force=mass x acceleration due to gravity
Force=10x9.8
Force=98N
Work=force x distance
Work=98 x 75
Work=7350J
