Given:-
To Find:-
Solution:-
Firstly we calculate the acceleration of the hammer.
As we know that acceleration is defined as the rate of change of velocity at per unit time.
• a = v-u/t
where,
v is the final velocity
a is the acceleration
u is the initial velocity
t is the time taken
Substitute the value we get
→ a = 0-60/0.015
→ a = -60/0.015
→ a = -4000 m/S²
Here, negative sign show retardation .
Acceleration of the hammer is 4000m/s²
Now, Calculating the Force
• F = ma
Substitute the value we get
→ F = 0.6×4000
→ F = 6×400
→ F = 2400 N
Therefore, the force applied by the hammer on the nail is 2400 Newton.
