Answer:
mass of the other asteroid =
Explanation:
We use the definition for the force between two celestial objects under the action of the gravity they produce using newton's general gravitational constant:
The force between the two asteroids will then be given by:
where G is Newton's gravitational constant, the asterioid's masses are M1 and M2 respectively, and d is the distance between them.
We replace the known values in he equation above, and solve for the missing mass:
Since the units for the given quantities are all in the SI system, our resultant units for the unknown mass of the asteroid will be in kg.
Answer:
Explanation:
Given data
Mass m=5 kg
Moment of Inertia I=0.0648 kg.m²
Radius r=0.18 m
Linear Speed v=4.8 m/s
To find
Total Kinetic Energy K.E
Solution
The total kinetic energy K.E can be found as below
First we need to find the angular speed ω
So
Substitute the angular speed and given values to find total kinetic energy
So
Answer:
Velocity between points A and B will be 0.2344 m/s
Answer:
g= 1.8 m/s²
Explanation:
From conservation of energy we know:
Solving for g with h being the height of the ramp with angle ∅ and length L:
(1)
The velocity v at the bottom of the ramp for a constant acceleration a in a time t is given by:
(2)
Plugging equation 2 in to equation 1:
(3)
