Answer to Problem 13.148P
When anvil has infinite mass, the energy absorbed by the rivet is
The impulse exerted on the rivet is
Explanation of Solution
Given information:
Weight of hammer is
The velocity of the rivet is
“A force acting on a particle during a very short time interval but large enough to produce a definite change in momentum is called an impulsive force.”
Impulse momentum principle for impulsive motion is defined as
The total linear momentum of two particles is conserved. Therefore
Calculation:

- How to solve this?arrow_forwardA start-up company wants to convert an ICE vehicle into an electric vehicle with the following specification. Power: 250 (HP) horsepower, (note: 1HP = 745 W) Range: 300-miles Fuel economy: 33.5 kilometers per gallon of gasoline. Efficiency of the ICE: 25% Energy Conversion: One gallon of gasoline at 100% efficiency is equal to 33.5 kWh/gallon). a)Calculate the EV consumption rate as Wh/km and find the total energy of the battery pack in KWh to replace the internal combustion engine. b)Design an 8-module battery pack for this full electric vehicle without compromising its range and performance (power). Use commercially available cylindrical cells lithium cell with 20Ah capacity and 3.125 V average voltage. Cell dimensions are 5cm diameter and 10 cm height.
