Sagot :
Answer:
-135m/s
Explanation:
Impulse P=change in momentum
Let the final velocity be -Vf (negative sign due to opposite direction)
Average force =Impulse/Time
=m(-Vf-Vi)/t
=>0.15m.g (-Vf-45)/0.003=4500N
=>0.15 (-Vf-Vi)=13.5
=>(-Vf-Vi)=90
Given,Vi=45
=>(-Vf) =90+45
=>(-Vf)=135
=>Vf = -135m/s
Hope it helps!!!
The velocity of ball coming off the bat will be -135m/s. Negative shows the direction.
What is velocity?
The change of distance with respect to time is defined as velocity. It is a time-based component. Its unit is m/sec.
The given data in the problem is:
m ( mass) =0.15 Kg
u is the initial velocity of fall =45 m/sec
v is the final velocity= ?
From the Newton's second law of motion;
Impulse = change in momentum
[tex]\rm I= \triangle P \\\\ Ft = m(v-u) \\\\ 4500=\frac{0.15(V-45)}{0.003} \\\\ V = -135 \ m/sec[/tex]
Hence,the velocity of ball coming off the bat will be -135m/s.
