A) travel outside the necleus
Answer:100joules
Explanation:
Mass(m)=5kg
Acceleration due to gravity(g)=10m/s^2
Height(h)=2 meters
Work=m x g x h
Work=5 x 10 x 2
Work=100joules
At the end of the laps, the runner's displacement is zero.
Answer:
The horizontal range will be
Explanation:
We have given initial speed of the shell u =
Angle of projection = 51°
Acceleration due to gravity
We have to find maximum range
Horizontal range in projectile motion is given by
So the horizontal range will be
