A particle moves with acceleration function a(t) = 5 + 4t - 2t^2. Its initial velocity v(0) = 3 m/s and its initial displacement
is s(0) = 10 m. Find its position after 4 seconds.
1 answer:
Answer:
Its position after 4 seconds is 62 meters.
Explanation:
It is given that,
The acceleration of the particle is given by equation :

Also, 



At t = 0,
. So, c = 3

Also,
, s is the position



At t = 0,
. So, c' = 10

At t = 4 s

s = 62 m
So, at t = 4 seconds the position of the particle is 62 meters. Hence, this is the required solution.

The answer is D. 32 m.
The simple equation that connects speed (v), time (t), and distance (d) can be expressed as:

The answer is Monocline. And I checked it, it's correct.
Answer:
The planet Jupiter completes one revolution of the sun in 362710000 seconds. Long time, right?
Explanation:
3.154x10^7=3.154x10000000=31540000
11.5x31540000=362710000
Number a is a correct one
