Answer: The speed at which Maya threw the snowball at Max is 20m/s
Explanation:
Given that
Mass of snowball= 1.5-kg.
Mass of Maya= 12kg
Initial speed of Maya=2.5m/s
We use the law of conservation of momentum to calculate the speed of the snowball which depends on its own mass, the mass of Maya who threw the snowball and the initial velocity at which the snowball was thrown by Maya
Ms x Us = Mm x Um
Mass of snowball x Initial speed of Snow ball =Mass of Maya x Initial speed of Maya
1.5kg x Initial speed of Snow ball =12 kg x 2.5m/s
Initial speed of Snow ball=( 12 kg x 2.5m/s) /1.5kg
Initial speed of Snow ball =20m/s
Answer:
momentum formula = Mass × Velocity
Answer:
Explanation:
According to the <u>Third Kepler’s Law</u> of Planetary motion:
(1)
Where;:
is the period of the satellite
is the Gravitational Constant and its value is
is the mass of the Earth
is the semimajor axis of the orbit the satllite describes around the Earth (as we know it is a circular orbit, the semimajor axis is equal to the radius of the orbit).
On the other hand, the orbital velocity is given by:
(2)
Now, from (1) we can find
, in order to substitute this value in (2):
(3)
(4)
(5)
Substituting (5) in (2):
(6)
(7) This is the speed at which the satellite travels
I’d say 4 because running a mile in 6 minutes is better than what most people can do and that will really make your heart rate go up
