A) Equivalent resistance increases
b) Current through entire circuit decreases
c) Current through the two ( 55 and 75 resistors remains the same), current through 45-resistor is 0.2A
<span>v = (22/15)*98 = 143.7 ft/sec
For no friction, Θ = arctan[v²/(R*g)] = 32.68°
Anet = √[(v²/R + g²] = 33.2 ft/sec²
Af = Anet*sinΘ = 17.93 ft/sec²
Ff = m*Af = (3200/32.2)*Af = 1781.9 lb along the slope.
Fr = Ff*cosΘ = 1500 lb</span>Source(s):<span>Free body diagram

Velocity refers to the change in the position of the object with time.
<h3>What is the velocity?</h3>
The term velocity refers to the change in the position of the object with time. In this case, we have the position time graph that we could use to obtain the velocity of the body at any interval. The velocity is the slope of the position time graph.
4) velocity of the toy car from 0-3 seconds;
v = Δx/Δ t = 3 - 0/ 1.5 - 0 = 2 m/s
5) velocity of the toy car from 5-8 seconds
v = Δx/Δ t = 6 - 3/8 - 5 = 3/3 = 1 m/s
6)
v = Δx/Δ t = 0 m/s
