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>
I need points sorry so idek the answer so u will have to ask someone else
its c because The microscopically colliding particles, that include molecules, atoms and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy.
Answer:
cuz he use parachute
Explanation:
free fall is when you are falling and accelerating with G, so as parachuist using parachute and decelerating it's not free fall.
