Answer:
The difference between frictionless ramp and a regular ramp is that on a frictionless ramp the ball cannot roll it can only slide, but on a regular ramp the ball can roll without slipping.
We will use conversation of energy.

Note that initial potential energy is zero because the ball is on the bottom, and the final kinetic energy is zero because the ball reaches its maximum vertical distance and stops.
For the ball B;


The initial velocities of the balls are equal. Their maximum climbing point will be proportional to their final potential energy. Since their initial kinetic energies are equal, their final potential energies must be equal as well.
Hence, both balls climb the same point.
Explanation:
Answer: <em>Powdered sugar</em>
Powdered sugar dissolves faster compare to the sugar cube. Because sugar cube has less surface area (the granules are tightly packed) compared to powdered sugar
I dont know from option
Because SI Unit of acceleration is m/s^2
The net force on the rocket is 864 N
Explanation:
The net force acting on the rocket can be calculated by using Newton's second law of motion, which states that:
F = ma
where
F is the net force on an object
m is the mass of the object
a is its acceleration
For the rocket in this problem, at a certain instant we have:
m = 48 kg

Therefore, the force on the rocket is
