Answer:
speed of the arrow as it leaves is 41.05 m/sec
Explanation:
We have given mass m = 0.285 kg
Average force F = 182 N
Distance traveled d = 1.32 m
We know that work done = force
distance
Sp work done = 
Now according to work energy theorem work done will be equal to kinetic energy
So 


v = 41.05 m/sec
So speed of the arrow as it leaves is 41.05 m/sec
Answer: B - Both electric and magnetic fields
Explanation: Ap*x verified just did the test and got it correct, answer is right infront of me at the moment
Answer:
c. 2.6 h
Explanation:
The longest time spent over dinner is the time that you have available minus the minimum possible time spent in the trip.
The time of the trip is found using:
t = 
Where distance is d and velocity is v. The time will be minimum at maximum velocity. Replacing with the data we have:
Ttrip =
= 8.1818 h
Tdinner = 10.8h - 8.1818 h = 2.6181h
that aproximates 2.6 h.
