Answer:
A. 1222,10 N
Explanation:
First, we determine the value of the acceleration that the hydraulic launching system must guarantee. Let’s remember that the definition of acceleration is the rate of change of velocity with respect to time. Therefore:
a_hyd = ∆v/∆t = (54 m/s-0)/(3,8 s-0) = 14,21 m/s^2
According to Newton’s second law:
∑F_net = m*a = 86 kg*14,21 m/s^2 = 1222,10 N
So, the net force required to accelerate an 86-kg man is 1222,10 N
Have a nice day! :D
It bounces off one another and goes back in forth

Light Independent Reactions
Answer:
glass if for a good view, but for absorbing heat concrete and brick is the best
Explanation:
wood is not a good idea bc it can cause fires from too much heat and it absorbs less heat but all of that depends on how good the material your using
