Answer:2058.992KJ
Explanation:
Given data
Mass of object
=521kg
initial velocity
=90m/s
Final velocity
=14m/s
kinetic energy of body is given by=


change in kinectic energy is given by substracting final kinetic energy from initial kinetic energy of body.
Change in kinetic energy=

Change in kinetic energy=

Change in kinetic energy=2058.992KJ

Answer:
Integrated development spends more money up front to order to save money in later stages.
Explanation:
The primary difference between integrated/concurrent engineering development and functional/sequential development is: Integrated development spends more money up front to order to save money in later stages.
Cost of integrated development is higher in the initial stages where setup has be made and proper training and education of employees are required and once it is done. It will save money in later stages.
