Complete Question
Suppose you hit a steel nail with a 0.500-kg hammer, initially moving at 15.0 m/s and brought to rest in 2.80 mm. How much is the nail compressed if it is 2.50 mm in diameter and 6.00-cm long.What Average force is excreted on the Nail
Answer:
Explanation:
From the question we are told that:
Mass
Initial Velocity
Distance
Diameter
Length
Generally the equation for Force is mathematically given by
Answer:
The formula is dimensionally correct.
Explanation:
Given
Required
Prove its correctness
Write out the dimension of each:
--- displacement
--- velocity * time
--- acceleration * square of time
The expression becomes:
Apply law of indices
Both sides of the equation are equal
