Question

The force applied on M by 1kg is 50N and applied on m by 2kg is 65N​ 1)the contact force between 2 kg and 1 kg 2)the masses M and m are

Answer 1

The contact force between M and m is 21.6 N.

The masses M and m are 2 kg and 1 kg.

Explanation:

Given that,

Mass on M = 2 kg

Mass on m = 1 kg

Force on m= 50 N

Force on M = 65 N

The force on M is greater then m.

We need to calculate the acceleration of the blocks

Using formula of force

$F= ma$

$a=\dfrac{F}{m}$

Put the value into the formula

$a=\dfrac{65}{2+1}$

$a=21.6\ m/s^2$

We need to calculate the contact force between M and m

Using formula of force

$F = ma$

$F=1\times21.6$

$F= 21.6\ N$

(II). According to question,

The masses M and m are 2 kg and 1 kg.

Hence, The contact force between M and m is 21.6 N.

The masses M and m are 2 kg and 1 kg.
