Answer: This will be based on how much strength she put into the rock when throwing it
Explanation:
Speed=distanse/time
144/12=12
ans is 12m/s
A dishwasher and a dryer im not sure if that is right but that’s what I would put
A magnetar. It is a neutron star that has an amazing strong magnetic field.
I hope this helps!
Given the equation for the Speed of a Satellite
v = SqRt{Gravitational Constant}{Mass of Earth} divided by the radius given in your problem
we have:
(square root whole term on right side)
v = G Me
———
r
so. (6.67x10^-11)(5.97x10^24)
___________________
(8.0x10^6)
v = 7055 m/s (which is reasonable)
so utilize the Kinetic Energy Formula
KE = 1/2mv^2
KE = 1/2(200)(7055)^2
KE = 4.977x10^9 J
