Answer:
a). The velocity of the first log is -1.65 m/s.
(b). The velocity of the second log is 1.07 m/s.
Explanation:
Given that,
Mass of lumberjack M= 110 kg
Mass of log m= 206 kg
Final velocity = 3.09 m/s
(a). We need to calculate the velocity of the first log just before the lumberjack jumps off
Using conservation of momentum
Put the value into the formula
The velocity of the first log is -1.65 m/s.
(b). If the lumberjack comes to rest relative to the second log
We need to calculate the velocity of the second log
Put the value into the formula
The velocity of the second log is 1.07 m/s.
Hence, (a). The velocity of the first log is -1.65 m/s.
(b). The velocity of the second log is 1.07 m/s.
Answer: (2) 108 C
Explanation:
Electric charge of 1 coulomb has said to have passed when a current of 1 Ampere is passed for 1 second.
Q= charge in coloumb = ?
I = current in amperes = 0.120 A
t= time in seconds = 900 sec
