Newton of motion
Initial k.e = ½*20*4*4 = 160j Final k.e = 2*160 = 320j Final Velocity = √(2*320)÷20 = √32 m/s = 5.66m/s Ft = m(v-u) t = 20(√32-4)÷5 t = 6.64s
Initial k.e = ½*20*4*4
= 160j
Final k.e = 2*160
= 320j
Final Velocity = √(2*320)÷20
= √32 m/s
= 5.66m/s
Ft = m(v-u)
t = 20(√32-4)÷5
See lesst = 6.64s
Factors affecting capacitance
1. Area of overlap. 2. Distance of separation. 3. The nature of dielectric material.

A ball thrown vertically from a moving vehicle
The ball will fall into the open moving car. This is because the constant velocity of the open moving car is equivalent to the velocity with which the projectile moves.
