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

Explanation: Hope this helps
Answer:
38kJ
Explanation:
Final Energy= Total Energy at the beginning + Total energy added - energy lost
Final Energy = 12.5 + 500/1000 + 30- 5
= 38kJ
Answer:
I think the answer is A. HIV
