It would be a) 2 electrons
Answer:
0.6944 m/sec^2
Explanation:
The computation of the average acceleration is given below:
a = v - u ÷ t
where
a denotes average acceleration
v denotes final velocity
u denotes initial velocity
t denotes time
So, the average acceleration is
= (25 - 0) ÷ 10
= 0.6944 m/sec^2
By balancing the force, we get :
100 - Frictional Force = ma
100 - μmg = ma
100 - μ(5)(10) = (5)(15)
50μ = 25
μ = 0.5
Distance travelled by box in 5 seconds is :
Hence, this is the required solution.
