Question

An object A is dropped from the top of a 30m high building and at the same moment another
object B is projected vertically upwards with an initial speed of 15 m/s from the base of the
building. Mass of the object A is 2 kg while mass of the object B is 4 kg. Find the maximum
height above the ground level attained by the centre of mass of the A and B system (take g = 10
m/s)
b) 10m
c) 15m
d) 20m
a) 5m​

Answer 1

Answer:

10m

Step-by-step explanation:

An object A is dropped from the top of a 30m high building and at the same moment another

object B is projected vertically upwards with an initial speed of 15 m/s from the base of the

building. Mass of the object A is 2 kg while mass of the object B is 4 kg. Find the maximum

height above the ground level attained by the centre of mass of the A and B system (take g = 10
