Answer:
(Downwards)
(Towards Left)
Explanation:
As we know that beam is in equilibrium
So here we can use torque balance as well as force balance for the beam
Now by torque balance equation at the pivot we can say
As we know that
mg = 1.40 kN
F = 5 kN
so we will have
Now force balance in vertical direction
(Downwards)
Force balance in horizontal direction
(Towards Left)
Inclined Component of the bicyclist's velocity:
Vi = 500/10 = 50 m/s
Vertical Component of the bicyclist's velocity:
(This is simply the cosine of the Vc)
Vv = 50Sin30 = 25 m/s
The vertical velocity is 25 meters per second.
They are two different mirrors but are very similar. concave are like those round kinds that make stuff look big and convex mirrors are those that look like cameras that pop out.
Answer:
38.8 km/hr
Explanation:
The total distance is 2 × 282 km = 564 km.
The total time is 6 hr 32 min + 8 hr = 14 hr 32 min = 14.533 hr.
The average speed is:
(564 km) / (14.533 hr)
38.8 km/hr
