The resultant of the two forces is about 170 N.
<h3>What is the resultant force?</h3>
The term resultant force has to do with the single force that has the same magnitude and direction as two or more forces acting together.
In this case, the both forces are acting in the forward direction. This implies that the resultant force is 90 N + 80 N = 170 N.

<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.

Answer:
162 KJ
Explanation:
The electrical energy can be calculated using the formula
E = V×I×t
Where, V= voltage = 120 V
I is current in ampere = 7.5 A and t is time in seconds
1 hour = 3600 sec
Therefore, 0.05 hour = 3600×0.05 = 180 sec
Substitute the values in above equation find electrical power
E = 120×7.5×180
= 162000 J
= 162 KJ
Therefore, the electrical energy use of the microwave = 162 KJ
The average speed of the car would be 50 mph
