Answer:
Maximum speed, v = 36 m/s
Explanation:
Given that,
The radius of the curved road, r = 120 m
Road is at an angle of 48 degrees. We need to find the maximum speed of stay on the curve in the absence of friction. On a banked curve, the angle at which it is cant is given by :
g is the acceleration due to gravity
v = 36.13 m/s
or
v = 36 m/s
So, the maximum speed to stay on the curve in the absence of friction is 36 m/s. Hence, this is the required solution.
Answer:
61.803 Newtons
Explanation:
m = Mass of crate = 21 kg
= Coefficient of kinetic friction between the crate and the floor = 0.3
g = Acceleration due to gravity = 9.81 m/s²
Force
So, the magnitude of force must the worker apply is 61.803 Newtons
