Answer:
B) collision is inelastic because they stick together after collision and share a common final velocity Vf
C) M1V1 + M2V2 = (M1 + M2)Vf
D) Vf = 6.33m/s
E) force = 3040N
Explanation:
Detailed explanation and calculation is shown in the image below
Explanation:
Given that,
Current of clothes dryer, I = 16 A
Voltage, V = 240 V
Time, t = 45 min = 2700 s
Current of personal computer, I' = 2.7 A
Voltage, V' = 120 C
Energy used by clothes dryer is given by :
Let t' is the time for this computer to "surf" the internet. Again using formula of energy used as :
So, for 8.83 hours you could use this computer to "surf" the internet.
