Cross-sectional area 
Let the tensile modulus of Nickel 
.
The elongation of the rod can be calculated using the following formula:
Answer:
2592 km/h
Explanation:
Given that a bullet is shot from a rifle with a velocity of 720 m/s. What is the velocity of the bullet in km/h.
The velocity = 720 m/s
Solution
To convert metres per second to kilometer per hour, you will multiply by 3600 and divide by 1000
720 × 3600/1000
720 × 3.6
72 × 36
2592 km/h
Therefore, the velocity of the bullet in kilometer per hour is 2592 km/h
