Answer:
Part a)
Part b)
So this speed is independent of the mass of the rider
Explanation:
Part a)
By force equation on the rider at the position of the hump we can say
now we will have
now we have
Part b)
At the top of the loop if the minimum speed is required so that it remains in contact so we will have
at minimum speed
So this speed is independent of the mass of the rider
Answer:
b) The downward force of gravity
Explanation:
The gravity force has the biggest influence on the deceleration of the ball because no matter how much force you applied on the ball, it will eventually go down again, according to newton's second law:
right after you throw the ball, only the force exerted by the gravity will affect the ball (neglecting air resistance):
so the object will eventually be going down again.
1)solid
2)contact
3)conduction
4)Fluid
5)Less
6)More
7)Convection
8)Waves
9)Radiation
10)emit
11)absorb
Answer:
Part a)
Part B)
Part c)
Explanation:
Part a)
As we know that
so we will have
Part B)
Angular speed of the yo-yo
so we have
Part c)
Tangential acceleration is given as
