Answer: Perpendicular because the second line has a 2/3 slope and starts at 4.
Something that could be done is to tie a rope long enough to cross the river and send the two younger brothers across first, then have Mike pull the boat back across the river with the rope and him get in the boat and row it across the river with just himself and the gear.
Another option is you can unload some gear, put the boys in the boat, row them across the river, unload the two younger boys, go back for the rest of gear and load it into the boat then come back.
Hope this helps!
Answer:
1900 = k
Step-by-step explanation:
38=k/50
Multiply each side by 50
50 *38 = k/50 *50
1900 = k
Answer:
about 6230 N
Step-by-step explanation:
The mass is given to 3 significant figures, so we need a value for the acceleration due to gravity that is at least 3 significant figures. The standard value is 9.80665 m/s². Using that, the force is ...
... F = ma = (635 kg)(9.80665 m/s²) = 6227.22275 N
Since the mass is only good to 3 significant figures, the force must be rounded to that precision: 6230 N.
