Answer:
The acceleration is Zero
Explanation:
When the ball is thrown upward, its motion is against gravity and the gravitational force. Hence, it has its acceleration as - g.
The very instant that the ball hits the ceiling is the moment it's upward motion stops.
Hence, in that instant, it is motionless or static.
If it is static, then, definitely, velocity is Zero and acceleration is also Zero.
However, after the ball hits the ceiling, it begins to fall back to the ground. It falls in the same direction as the gravitational force and so, its acceleration is +g.
Answer:
Multiply the mass times the speed for both, then compare.I would expect the mass of the oil ship to be more than 10 times the mass of the car, in which case its momentum would be greater.

Explanation:
Given that,
Number of state = 3
(a). We need to calculate the total energy
Using formula of the total energy
Put the value of n
(b). L= n-1= 3-1 = 2
Using formula of angular momentum
(c). Maximum value l =2
We need to calculate the the angular momentum
Hence, This is required solution.
Explanation:
It is given that,
Mass of the rim of wheel, m₁ = 7 kg
Mass of one spoke, m₂ = 1.2 kg
Diameter of the wagon, d = 0.5 m
Radius of the wagon, r = 0.25 m
Let I is the the moment of inertia of the wagon wheel for rotation about its axis.
We know that the moment of inertia of the ring is given by :
The moment of inertia of the rod about one end is given by :
l = r
For 6 spokes,
So, the net moment of inertia of the wagon is :
So, the moment of inertia of the wagon wheel for rotation about its axis is . Hence, this is the required solution.
