Question

if V1 and V2 are the units of physical quantity and N1 and N2 or its numerical values then

Answer 1

if v1andv2are the unit
so.
v1v2==N1n2
hence n is papotional to 1/u

Answer 2

Answer:

Acceleration = (Final velocity - Initial velocity )/ Time

Acceleration = (0 - 50) /  5

Acceleration = -50 / 5

Acceleration = -10m/s^2
