Neporo4naja [7]3 years ago
8 0
The hang time of a projectile can be calculated solely by knowing the vertical component of the velocity of projection.

This is because all projectiles with the same vertical component of velocity are in flight for the same time.This is possible only if we are able to find the vertical component of velocity and the flight time with the given information.

3. A crew team rows a boat at a rate of 20 km/h in still water. Beginning at time = 0 minutes, the team rows for 30 minutes up a
Sindrei [870]
Going upstream against the current gives a net speed equivalent to the speed at still water minus the speed of the current. Consequently, the speed downstream gives a net speed equal to the speed at still water plus the speed of the current, making it travel faster. The solution is:

UPSTREAM

v = 20 - 1.5 = 18.5 km/h
t = 30 mins or 0.5 hours
distance = 18.5km/h (0.5 h) = 9.25 km

DOWNSTREAM
for the same distance of 9.25 km:

v = 20 + 1.5 = 21.5 km/h
t = 9.25km / 21.5 km/h = 0.43 hours or 25.8 mins  =  26 mins --> FINAL ANS.

Sonbull [250]
E = Q - W 
E = 1,400 - 600
E = 800

So the answer would be 800J.
