Answer:
Explanation:
Impulse and Momentum
They are similar concepts since they deal with the dynamics of objects having their status of motion changed by the sudden application of a force. The momentum at a given initial time is computed as
When a force is applied, the speed changes to and the new momentum is
The change of momentum is
The impulse is equal to the change of momentum of an object and it's defined as the average net force applied times the time it takes to change the object's motion
Part 1
The T-ball initially travels at 10 m/s and then suddenly it's stopped by the glove. The final speed is zero, so
The impulse is
The magnitude is
Part 2
The force can be computed from the formula
The direction of the impulse the T-ball receives is opposite to the direction of the force exerted by the ball on the glove, thus
2g/mL
Explanation:
Given parameters :
Mass = 10g
Volume = 5mL
Unknown:
Density of the object = ?
Solution:
Density is defined as the mass per unit volume of a body.
Density =
Now, input the values in the equation:
Density = = 2g/mL
