Answer:
Explanation:
The resultant would be a combination of the two forces. We need to add them together since they are exerting a force in the same direction.
10+30= 40 N of force
Answer:
momentum is directly proportional to acceleration
Answer:
(a) FN = m (g -
)
(b) vmin = 17.146 m/s
Explanation:
The radius of the arc is
r = 30m
The normal force acting on the car form the highest point is
FN = m (g -
)
If the normal force become 0 we have
m (g -
) = 0
or
g -
= 0
This way, when FN = 0, then v = vmin, so
g -
= 0
vmin =
= ![\sqrt[.]{9.8 m/s^{2} * 30m } = 17.146 m/s](https://tex.z-dn.net/?f=%5Csqrt%5B.%5D%7B9.8%20m%2Fs%5E%7B2%7D%20%2A%2030m%20%7D%20%3D%2017.146%20m%2Fs)
