A60kg girl standing on rollerskates (with no friction between the skates and the ground) throws a 5kg medicine ball to the right with a speed of 6m/s. find the recoil velocity of the skater.

The recoil velocity of the skater is V1= 0.5 m/s

Explanation:

m1= 60 kg

V1= ?

m2= 5kg

V2= 6 m/s

m1*V1 = m2*V2

V1= (m2*V2) / m1

V1= 0.5 m/s

none, its a machine

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
