Answer:
Explanation:
We can use the following kinematics equations to solve this problem:
.
Using the first one to solve for acceleration:
.
Now we can use the second equation to solve for the distance travelled by the airplane:
(three significant figures).
Answer:
I believe it is luminosity and distance
Explanation:
So B
Answer:
40,000N
Explanation:
Force = Acceleration × Mass
2000×20=40,000
Answer:
256.3 N
Explanation:
Throughout the motion of the mass in the circular motion, the resultant of the Tension in the string and the weight of the body gives the net force (centripetal force) that is responsible for the acceleration of the mass in a circular motion.
At the top of the vertical circle of the motion of the mass, the tension is directed downwards towards the centre of the circle and the weight also is directed downwards towards the earth.
Net force = ma = T + W
ma = T + mg
But a = (v²/r) for circular motion,
(mv²)/r = T + mg
m = 2.31 kg
v = 7.77 m/s
r = 0.500 m
g = acceleration due to gravity = 9.8 m/s²
(2.31×7.77²)/0.5 = T + (2.31×9.8)
278.923 = T + 22.638
T = 278.923 - 22.638
T = 256.285 N = 256.3 N
Hope this Helps!!!
