Answer 1

Answer:

g

Explanation:

Given Two particles of masses 2 kg and 4 kg are thrown

from the top of a tower such that first is vertically

upward and second is at angle 45° above

horizontal. Acceleration of the centre of mass of

two particle system is

Now acceleration of both particles are same, which is equal to acceleration due to gravity.

So m1 = 2 kg , m2 = 4 kg

And a1 = g , a2 = g

Acceleration of centre of mass = m1a1 + m2a2 / m1 + m2

                                                 = 2 x g + 4 x g / 2 + 4

                                                = 6 g / 6

                                                = g
