If the object is negatively charged it means it has gained electron so negatively charged object has more number of electron than proton
If the object is positively charged it means it has lost electron so positively charged object has more number of proton than electron
Let F be the force acting on the bowling ball.
Work done by force= change in KE
Let F be the force acting on the bowling ball
Work done by force = change in KE
F .d = 0.5 m V^2 + 0.5 x I x w^2
F d = 0.5 m ( 1+l) V^2
Solve accordingly to get the answer.

Answer:
v = 15 m / s
Explanation:
In this exercise we are given the position function
x = 5 t²
and we are asked for the average velocity in an interval between t = 0 and t= 3 s, which is defined by the displacement between the time interval
let's look for the displacements
t = 0 x₀ = 0 m
t = 3 
= 5 3 2
x_{f} = 45 m
we substitute
v = 15 m / s
