Question

At the same instant that a
0.50kg ball is
dropped from 25m above Earth, a second ball
with a mass of 0.25kg. is thlown upward
from Earth's surface with a initial speed
of 15m/s. what are the initial velocity &
acceleration
of center
of mass?​

Answer 1

Answer:

Explanation:

           com initial vel. = m1u1 +m2u2 /m1+m2

                                      = 15 x 0.25/0.75 = 5 m/s

                   its acc = m1 a1 + m2a2/m1+m2

                                 = 0.5 x 10/ 0.75 = 0.67 m/s²

     hope u get it n let me know.............................................
