Answer:
<h2>After 3.06seconds</h2>
Explanation:
Given that the following data are
acceleration a= 3,2m/s^2
distance s=15m,
time t=?
Applying the formula for the equation of motion we have
s=ut+1/2at^2
we no initial velocity (u=0)
substituting our given values into the expression we have
15=0*t+1/2(3.2)t^2
15=1/2(3.2)t^2
15=3.2t^2/2
30=3.2t^2
t^2=30/3.2
t^2=9.375
Squaring both sides we have
t=√9.375
t=3.06seconds
<em>It will take the sled 3.06 seconds to get to the bottom</em>
Under constant acceleration, we have average velocity over a time interval of duration satisfying
where are the plane's initial position and velocity (respectively) and are the plane's position and velocity (respectively) after 9.00 seconds. So
Answer:
Disagree
Explanation:
We cannot see infared lights.
The best answer is B. If you curve them away, they have a less tendency to be attracted to the pair of charges and would stay around the pair instead of interacting with them.
