Answer:
larger, because her angular speed is larger.
Explanation:
The rotational kinetic energy is proportional to the square of the angular velocity while it is linearly proportional to the moment of inertia. So the increase of angular speed will have a larger effect of the kinetic energy than the decrease of the moment of inertia.
Answer:
7.75m/s or 
Explanation:
m = 1.5kg
u= 10m/s
s = 2m
a = 
v = ?
acceleration due to gravity is negative when an object is going up because the force of gravity reduces the speed of the object
using the formula ;
since the object is moving upwards (negative acceleration)
= 100 - 2(10)(2)
100 - 40
= 60
v = 
= 7.75m/s
B. When the sun and the moon are aligned, their combined gravitational force attracts the water, causing super high tides on one side of the planet, and super low tides on the opposite side.
