Atoy boat moving at 3.2 m/s accelerates at 6.5 m/s2. how fast will it go after 2.5 seconds?
(number)
(unit)

19.5 m/s

Explanation:

The boat is moving with a uniform accelerated motion, therefore we can use the following suvat equation:

where :

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

For the boat in this problem,

u = 3.2 m/s

Substituting t = 2.5 s, we find the final velocity of the boat:

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

this could be newton#'s law of cooling. the cooling curve is exponential
