Answer:8.8983N
Explanation:
Horizontal component=9xcos19
Horizontal component=9x0.9887
Horizontal component=8.8983N
Total resistance will be R1 + R2.
And the formula will be I equals V over R.
V=5
I=?
R=6
I= 0,83 amps
Let us consider the air with the index 1 and the lucite with index 2. Using the Snell's Secound Law, we have:
Entering the unknowns, remembering that the air refrective index is 1 and the lucite refrective index is 1.5, comes:
Using the arcsin properties, we get:

Given that the velocity of a car increases by 40 m/s in 80 seconds, the acceleration of the car will be given by:
a=(final velocity-initial velocity)/(time)
thus;
final velocity=40 m/s
initial velocity=0
time=80 seconds
hence;
a=(40-0)/80
=0.5m/s^2
