We are given with
l = 8.00 m
θ = 37.0°
m = 470 kg
r = 0.300 m
μ = 0.120
To solve the magnitude of the force required to roll the cylinders up the ramp, we do a force balance
F = Ff
F = μFn
F = mgμ sin θ
substituting the given values
F = 470 (9.81) (0.120) sin 37.0°
F = 333.97 N<span />
A roller coaster is stopped on a track. When the engineer presses a launch button on the coaster, the coaster moves forward. Explain this change in terms of balanced and unbalanced forces.
Answer:
Cinder blocks
Explanation:
From safety training guides, whenever there is inadequate support, poor
construction, or a movement in the components of the
scaffold such as the coupler as well as the base upon which the
scaffold structure is built, there will be a great danger of collapse.
In light of this safety rule, Cinder blocks such as sandcrete blocks, bricks e.t.c shouldn't be used to support scaffold because they
have a high tendency of being crushed under load
Answer:
<em>1988.05 rad/s^2</em>
<em></em>
Explanation:
The angular speed of the optical disk ω = 998.0 rad/s
the time taken to come to rest t = 0.502 s
The magnitude of the average angular acceleration ∝ = ω/t
∝ = 998.0/0.502 = <em>1988.05 rad/s^2</em>
