Answer:
The ball takes 5s to reach the ground
Explanation:
in order to solve this problem we use the kinematics equation with gravity as acceleration:

we replace the values

We solve this quadratic equation:
t=5s
t=-6s (this solution has not physical sense)
Explanation:
The answer is D. Drivers must always yield to pedestrians and bicylists coming off a main road and always yield to emergency vehicles with lights on. Vehicles in a funeral must have lights on to alert other drivers of their pace and procession.

Explanation:
Given:


Let's write the components of the net forces at the intersections. Note that the system is equilibrium so all the net forces are zero.
<u>Forces</u><u> </u><u>involving</u><u> </u><u>W1</u><u>:</u>


<u>Forces</u><u> </u><u>involving</u><u> </u><u>W2</u><u>:</u>


Substitute (2) into (3) and we get

Solving for
