Answer:
v = 2.41 m/s
Explanation:
Here net force on the Skater + snowball is zero
so here we can use momentum conservation for skater + snowball
now we have
so the final speed of skater will be 2.41 m/s
They hold everything together. They may be small, But they do the biggest part.
F=Gm1m2/r^2 where G is a gravitational constant
F≈m
the greater the mass of planets, the greater the gravitation force experiment by a person
gravity of a planet (a=GM/r^2)
the larger the mass of planet , the larger the gravity of planet
Weight = mass * gravity of the planet
therefore when neutron star has the same mass as our sun, the mass is larger and the gravity of it will be very large
Answer:
v = 49.05 m/s^2
Explanation:
Let's use the uniform acceleration equation to find our final velocity.
v = final velocity
u = initial velocity
a = gravitational acceleration
t = time taken
Assuming the rock is at rest initially, u becomes zero.
