So the velocity of ball b is 6.50kg then just simple reciprocate the kgm of ball A
Answer:
Explanation:
just use the gravational force equation which is G x m of earth x m of object divided by r squared (which is radius of earth)
The first image below shows force F1 and the axes.
Answer:
3.62 kN
Explanation: The second figure below express the parallelogram method to calculate the u component of force F1.
The <u>Parallelogram</u> <u>Method</u> is a method to determine resultant force and is applied as described in the question above.
With the three components,
and
and angles, it can be used the <u>Law</u> <u>of</u> <u>Sines</u>, which states:

i.e., there is a relation of proportionality between an angle and its opposite side.
For the triangle below:



u = 3.62
The magnitude of the component acting along the u-axis is 3.62kN.
Kinetic energy = 1/2 (mass)*(velocity)^2
ke = 1/2 (1500kg) (17m/s)^2
ke = 216750 kg*m^2/s^2 = 216750 Joules
(sorry, I don't know significant figures. but this is otherwise the correct answer with the right units. hope this helps!! :))
The story sure is exciting. But when you're ready to work on answering the question, you can ignore everything before the assumptions.
-- When the pilot hit the snow, he was allegedly falling at 50 m/s.
-- His mass is 85 kg.
-- So his kinetic energy was (1/2) (mass) (speed squared) =
(1/2) (85) (50)² = <em>106,250 joules</em>
-- That's the energy that something else has to absorb in order to
reduce his speed to zero.
-- How far he fell, or what size crater he made in the snow, are irrelevant.
