Answer:
F = 33.12 N
Explanation:
given,
first force = 15 N is oriented at 58.0° counterclockwise
second force = (−19.0 N,18.5 N)
x-component of first force = 15 cos 58.0° = 7.95 N
y-component of second force = 15 sin 58.0° = 12.72 N
second component
now,
F netx = 7.95 - 19 = -11.05 N
F nety = 12.72 + 18.5 = 31.22 N
F = 33.12 N
θ = -70.51°
Use pythagorean theorem and inverse tangent.
a) magnitude - 29.15; angle - 59 degrees
b) magnitude - 234.09; angle - 110 degrees
c) magnitude - 0.4; angle - south
d) magnitude - 234.3; angle - 309.81 degrees
e) magnitude - 42.43; angle - 315 degrees
Answer:
b is correct.
Explanation:
because of the question you have given
Think Critically: Suppose a car is accelerating so that its speed is increasing. Describe the plotted line of the motion of the car on a distance-time graph. The plot would be a curved line sloping upward whose slope is increasing.
Area of parallelogram is b*h=0.952. There are 9500 of them so 0.952*9500=904.4 (answer c)
