Question 313.5 Points
What is the impulse on the ball?
-
Question 323.5 Points
What is the speed of the ball immediately after it leaves the bat?
Given data:
The mass of the ball is: m = 120 g
The speed of ball is: u = -35 m/s
The final velocity of the ball is: v
The impulse is: I
Q-29) The impulse can be found from the area under the graph.
Thus, the potion (2) is correct.
Q-30) The time is given in millisecond. Thus, the time has to be converted into the S.I. Unit second. Thus, option (2) is correct.
