Answer:
Ball 1 has a mass of 0.5 kilogram and an initial velocity of 1.00 meter/second. Ball 2 has a mass of 1.5 kg and an initial velocity of 0.00 meters/second.
Explanation:
Answer:
r = 9.92 mm
Explanation:
Given that,
Mass of oil drop,
It acquires 2 surplus electrons, q = +2e
Potential difference, V = 620 V
Thie potential difference is applied between the pair of horizontal metal plates the drop is in equilibrium.
We need to find the distance between the plates.
At equilibrium,
mg = qE
Since, E = V/r (r is distance between plates)
So, the distance between the plates is 9.92 mm.

Explanation:
Answer: The train traveled 210 miles in 6 seconds of time duration.
Explanation:
The initial velocity of the train,u = 50 mile/s
Acceleration of the train ,a =
Duration of time ,t = 6 seconds
Using second equation of motion :
The train traveled 210 miles in 6 seconds of time duration.
Answer:
4 %
Explanation:
mass of the object 1, m₁ = 0.1 Kg
initial velocity of object 1,v₁= 0.2 m/s
mass of object 2, m₂ = 0.15 kg
initial speed of the object 2. v₂ = 0 m/s
Kinetic energy retained by the object 1 = ?
using the formula to calculate velocity of the ball after collision
negative sign represent the velocity is in opposite direction after collision.
Initial KE
final KE
% of KE retained
=
=
= 4 %
the percentage of Kinetic energy retained after collision is equal to 4 %
