The principle of moment can be verified when two known masses are suspended on a uniform meter rule.
<h3>What is principle of moment?</h3>The principle of moment states that, the sum of clockwise moment is equal to the sum of the anticlockwise moment.
The principle of moment is verified when two known mass (m1 and m2) are suspended on a uniform meter rule.
The clockwise moment will be equal anticlockwise moment of the two masses.
Thus, the principle of moment can be verified when two known masses are suspended on a uniform meter rule.

Answer:
Truck's speed = 5.21 m/s
Car's speed = 20.2 m/s
Explanation:
Given:
Mass of truck = M = 1650 kg
Speed of the truck initially = U = 15 m/s
Mass of the car = m = 779 kg
Initial speed of the car =u = 0
From the momentum conservation, Total initial momentum = Total final momentum.
M V+m U = M V +m v
⇒ (1650)(15) + 779×0 = (1650)V + 779 v
⇒ 24750 = 1650 V+779 v →(1)
Since the collision is elastic, relative velocity of approach = relative velocity of separation. 15 = v - V
⇒ v =V + 15; This is now substituted in the equation(1) above.
24750 = 1650 V + (799) (V+15)
⇒ 24750 = 1650 V + 799 V + 11985
⇒ 2449 V = 12765
⇒ Final velocity of the truck = = 5.21 m/s
Final velocity of the car = v = V+15 = 5.21 + 15 = 20.2 m/s
