Answer:
B) 20N.s is the correct answer
Explanation:
The formula for the impulse is given as:
Impulse = change in momentum
Impulse = mass × change in speed
Impulse = m × ΔV
Given:
initial speed = 40m/s
Final speed = -60 m/s (Since the the ball will now move in the opposite direction after hitting the bat, the speed is negative)
mass = 0.20 kg
Thus, we have
Impulse = 0.20 × (40m/s - (-60)m/s)
Impulse = 0.20 × 100 = 20 kg-m/s or 20 N.s
The impulse experienced by the ball is,
[tex]\rm Impulse = 20\; Nsec[/tex]
Given :
Mass = 0.20 Kg
Initial Speed = 40 m/sec
Final Speed = -60 m/sec (minus sign shows that ball move in opposite direction)
Solution :
We know that the formula of Impulse is,
[tex]\rm Impulse = m\times \Delta V[/tex]
where, m is the mass and [tex]\rm \Delta V[/tex] is change in velocity.
[tex]\rm Impulse = 0.20\times(40-(-60))[/tex]
[tex]\rm Impulse = 20\; Nsec[/tex]
