Answer :
It is 1.5 m/s to the left
(1 m/s)(2 kg + 1 kg) - (1 kg)(0 m/s))/2 kg = 1.5 m/s to the left
(1 m/s)(2 kg + 1 kg) - (1 kg)(0 m/s))/2 kg = 1.5 m/s to the left
The velocity of the cart is 1.5 m/s to the left if the 2.0 kg cart moving in a straight line hits a piece of modeling clay (1.0 kg) that is at rest.
What is mass?
A tangible body's mass is the amount of matter it possesses. It's also a metric of inertial or the resistance to velocity when a net force is exerted.
We have:
A 2.0 kg cart moving in a straight line hits a piece of modeling clay (1.0 kg) that is at rest. The clay sticks to the cart and both move to the left at 1.0 m/s
By conservation of linear momentum:
= [(1 m/s)(2 kg + 1 kg) - (1 kg)(0 m/s)]/2 kg
= [3 - 0]/2
= 1.5 m/s (left side)
Thus, the velocity of the cart is 1.5 m/s to the left if the 2.0 kg cart moving in a straight line hits a piece of modeling clay (1.0 kg) that is at rest.
