Answer:
Increase
Explanation:
The acceleration will increase more if all the friction were removed from ramp.
Acceleration is the rate of change of velocity with time.
Frictional force is a force that opposes motion of a body.
- A large friction will reduce the velocity of a body significantly and bring it to stop, a state of no acceleration.
- When friction is removed, the acceleration of a body will increase significantly since the velocity will change rapidly.
- At each turn of time, the velocity keeps increasing due to absence of the inhibiting force of friction.
Part 1
If water does not spill at the top point of the circular motion then for the minimum speed condition we can say normal force will be zero at the top position



given that
R = 1 m
g = 9.8 m/s^2
now from above equation we have

Part b)
for minimum value of angular speed we will have
