WILL MARK BRAINLIESTT!! Experiment by hanging your first object (object 1) on the hook. Hold on to the cardboard, and position the cardboard and string so the object dangles just off the edge of the table. Then let go of the cardboard. If it moves, stop it when it reaches the edge of the table. Repeat the steps by replacing object 1 with object 2 on the hook. Finally, hang object 1 and object 2 together on the hook and repeat the steps. What do you observe when you hang different objects from the hook? What happens when two or more objects are on the hook together?

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
