Answer:
d = 220 m (2 s.d.)
Explanation:
If the arrow flies over a horizontal plain and air resistance is ignored.
The time of flight is twice the time that gravity takes to reduce initial vertical velocity to zero
t = 2(47sin37)/9.8 = 5.7725... s
Range is the time of flight times the initial horizontal velocity.
d = (47cos37)5.77 = 216.676...
The switches could be defective or worn out or the wires at the switch connections could be loose, causing arcing that is making the noises. There is probably nothing wrong with your basic wiring. ... The safest course is to replace any switch that is making unusual noises such as hissing, crackling and popping
Answer:
dynamo generator could be the right ans
Velocity = distance/time taken
Velocity = 5(1000)/25(60)
Velocity = 3.33 m/s
