Answer:
9.801 m/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 39 ft/s
s = Displacement = 720 cm = 7.2 m
a = Acceleration
Converting to m/s
Equation of motion
Acceleration of the ball is 9.801 m/s²

Answer:
n= 16021.03 slaps
Explanation:
Using law of Energy conservation
E_{thermal}= Kinetic energy of hand
⇒
m_h= mass of the hand = 0.4 kg
v_h= velocity of the hand = 10 m/s
n= number of slaps
c= 4180 J/Kg °C
m= mass of chicken = 1 kg
Assuming all the energy of hand goes into chicken
Given Ti=0°C and T_f= 170 F= 76.66°C
Now putting the values in above equation to get n
n= 16021.03 slaps
