The change in velocity is 5m/s which added to the initial 3m/s makes the final velocity 8m/s
Distance = (3*5) + (1/2*1*5^2)= 15+12.5= 27.5m
Answer:

Explanation:
We are given that




Using 
We know that

In series



Substitute the values




Voltage across the 2.5 square cm wire=
Voltage across the 2.5 square cm wire=
Voltage across the 2.5 square cm wire=22.1 V
Answer:
m2 = 83.3 g
Explanation:
by conservation of momentum principle we have

as both sphere has same speed so 

from conservation of kinetic energy principle we have




substituting this value in above equation to get m2 value

solving for m2 we get

m_1 = 250 g

m2 = 83.3 g
