If the vessel in the sample problem accelerates for 1.00 min, what will its speed be after that minute? Calculate the answer in both meters per second and kilometers per hour.

Question

dumbcow · Answer

can you post the sample problem..that might help :)

otherwise, I need to know what the acceleration is, what the initial velocity is

dumbcow · Answer

the conversion from m/s to km/hr is  3600/1000 or 3.6

1977 off the coast of Australia, the fastest speed by a vessel on the water was achieved. If this vessel were to undergo an average acceleration of. 1.80 m/s.^2, it would go from rest to its top speed in 85.6s. What was the speed of the vessel?

anonymous · Answer

@dumbcow sorry for taking a long time. I wrote the sample question

dumbcow · Answer

thanks..hold on while i read and try to set it up for you

dumbcow · Answer

ok equation for velocity is:
$$v(t) = at +v_0$$
where a is acceleration and v_0 is initial velocity
since its starting at rest....v_0 = 0

so to find the speed, just plug in the amount of time and multiply by acceleration

dumbcow · Answer

speed = 1.8 * time
