Answer:
The answer to your question is: total energy = 30100.4 J
Explanation:
Kinetic energy (KE) is the energy due to the movement of and object, its units are joules (J)
Data
mass = 1280 kg
speed = 4.92 m/s
Force = 509 N
distance = 28.7 m
Formula
Work = Fd
Process
- Calculate Kinetic energy
- Calculate work
- Add both results
KE = 
KE = 15492.1 J
Work = (509)(28.7)
Work = 14608.3 J
Total = 15492.1 + 14608.3
Total energy = 30100.4 J
Answer:
final equilibrium temperature is 65.02 ◦C
Explanation:
Given data
milk = 12 g
temp milk = 7◦C
coffee = 175 g
coffee temp = 69◦C
to find out
final equilibrium temperature
solution
we apply here equilibrium condition i.e m c ΔT
milk mass × c × ΔT = coffee mass × c × ΔT
12 × 1 × (T- 7) = 175 × 1 × ( 69- T)
12T - 84 = 12075 - 175 T
187 T = 12159
T = 65.02
so final equilibrium temperature is 65.02 ◦C
I believe if you are so out of breath that you cannot talk while exercising, your exercise level is too intense. Intensity in exercise is how hard you work out. For example sprinting up a flight of stairs over and over again would be a high intensity workout. To measure the intensity of exercise one method would be to monitor the heart rate of the individual undertaking the exercise
