During the first part of a trip, a canoeist covered 65 km at a certain speed. he then traveled 27 km at a speed that was 4 km/h slower. if the total time for the trip was 8 hr, what was the speed on each part of the trip?

13 km/h for 65 km

9 km/h for the next 27 km

Explanation:

Velocity of canoe =x km/h for 65 km

Velocity of canoe =x-4 km/h for 27 km after covering 65 km

Total time taken = 9 hours

So,

Solving this quadratic equation we get,

Speed cannot be 2.5 as the speed will become negative for the 27 km stretch.

So, velocity of canoe is 13 km/h for 65 km and 9 km/h for the next 27 km

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
