Answer:
Explanation:
Let mass of bullet = m1 = 28g= 0.028 kg
mass of pendulum = m2 = 3.1 kg
Answer:
a = - 3.14[m/s^2]
Explanation:
To solve this problem we must use the following kinematic equation:
Now replacing:
The negative sign means the vehicle slows down.
Answer:
a. one line down one line to the right one live to the northwest from the object
b. t1=190 t2=310
Explanation:
A billiard ball strikes another of the same mass at rest and stops, and the second ball then moves with the same velocity as the first ball would be an example of an elastic collision. This type of collision conserve both kinetic energy and momentum. The kinetic energy before they collide is equal after the collision.
