Answer:
Fx = 22N
Explanation:
There are 2 possible scenarios for this problem:
1.- The 10N force is in the same direction of the acceleration. In this case the other force would be:
where F1 = 10N, m=6kg, a = 2m/s2
The negative result tells us that this is not possible.
2.- The 10N force is in the opposite direction of the acceleration. In this case the other force would be:
Forces are by the cable, gravity and normal force by the incline.
Answer:
Explanation:
The PE equation for a mass/spring system is
Δx² and filling in:
and
so
k = 26000 N/m
If the displacement from equilibrium changes more, the PE needed to compress it will also change.
gives us that
PE = 520J
Answer:
15.64 KN
Explanation:
Given
Mass of the elevator = 1.70 × 10³ kg = 1700 kg
acceleration of the elevator = - 0.6 m/s²
Tension in the cable = ?
The free body diagram is given in the attached image
The net force acting on a body accelerates the body in the same direction as that in which the resultant is applied.
Force balance,
ma = T - mg
1700 (-0.6) = T - (1700×9.8)
T = 16660 - 1020 = 15640 N = 15.64 KN
