The magnitude of the tangential force that acts on the pole due to the tension in rope is given as
T= weight x tan (theta) /2
Answer:
-78.4 cm
Explanation:
We can solve the problem by using the lens equation:
where
p is the distance of the object from the lens
q is the distance of the image from the lens
f is the focal length
Here we have
p = 80.0 cm
q = -39.6 cm (negative, because the image is on the same side as the object , so it is a virtual image)
Substituting, we find f:
Answer:
θ = 18.3°
Explanation:
The angle can be found by using the formula for the range of projectile motion:
where,
R = Horizontal Range = 8.75 m
u = launch speed = 12 m/s
g = acceleration due to gravity = 9.81 m/s²
θ = launch angle = ?
Therefore,
θ = 18.3°
Since this angle is less than 45°. Therefore, it is the smaller of the two possible angles an dit is the correct answer:
<u>θ = 18.3°</u>
