A pile driver falls freely from a height of 4.50 m above a pile. What is its velocity as it hits the pile? Remember to include your data, equation, and work when solving this problem.

9.4 m/s

Step-by-step explanation:

We are given that

Height of pile driver above a pile =h=4.5 m

Acceleration due to gravity=

According to law of conservation of energy

K.E=Potential energy

Substitute the values

m/s

Hence, the velocity of pile driver as it hits the pile=9.4 m/s

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35
