Question

A platform rotates with constant angular velocity of 1 rad/s. Two masses m1

2 kg and m2

= 1 kg

(m1

> m2

) slide without friction in a groove passing through the centre of platform. The initial accel-

eration of mass m1

is​

Answer 1

Thus the acceleration of mass is a =  3.3 m/s^2

Explanation:

We are given that:

• Mass "m1" = 2 Kg
• mass "m2" = 1 kg
• Angular velocity = 1 rad / s

To Find: Acceleration = ?

Solution:

a = m1 - m2 / m1 + m2 / g

a = 2 - 1 / 2 + 1 x 10

a = 1 / 3 x 10

a =  3.3 m/s^2

Thus the acceleration of mass is a =  3.3 m/s^2
