Answer:
A)
ms⁻¹
B)
J
C)
i)
ms⁻¹
ii)
ms⁻¹
iii)
ms⁻¹
Explanation:
A)
= velocity of center of hoop
w = angular speed of the hoop = 3 rads⁻¹
d = diameter of the hoop = 2.20 m
radius of the hoop is given as
velocity of center of hoop is related to angular velocity by the relation given as
inserting the values
ms⁻¹
B)
= moment of inertia of hoop
= mass of the hoop = 2.30 kg
= radius of hoop = 1.10 m
Moment of inertia of the hoop is given as
kgm²
Total kinetic energy is given as
J
C)
i)
= velocity at highest point
velocity at highest point is given as
ms⁻¹
ii)
= velocity at bottom
velocity at bottom point is given as
ms⁻¹
iii)
= velocity at right
velocity at right is given as
ms⁻¹
Answer:
23 m/s squared
Explanation:
The equation is d = 1.8x + 14. Substitute 5 to get your answer of 23.
Answer: 2.4 m/s
Explanation:use KE= 1/2 mv²
Derive to find v:
v = √ 2KE / m
= √ 2 ( 9 J ) / 3 kg
= 2.4 m/s
