The concept that we need to give solution to this problem is collision equation given by momentum conservation,
Our values are,
Then,
Part A) We can here note that the velocity for the puck is zero (there is not a velocity in that direction)
Part B ) We apply the same solution but know we note that in the collision for the Goalie the velocity is zero.
Hello! :)
Use the kinematic equation below to solve for the height of the building:
Where:
d = distance, or height of the building (m)
a = acceleration due to gravity (9.8 m/s²)
t = time (seconds)
Plug in the given values into the equation:
Answer:
Explanation:
As the final Kinetic energy is zero or less than initial kinetic energy, the collision must be inelastic.
In Inelastic collision both the bodies must stick together as final velocity is zero for both the bodies.
To conserve the momentum, momentum associated before the collision of first must be equal and opposite to the momentum associated with the second ball.
