(i) |α| = 235.6rad.s / 0.502s = 469 rad/s²
(ii) tang a = α*r = 469rad/s² * 0.12m / 2*11 = 2.56 m/s²
Answer:
In Newtonian mechanics, the gravitational energy possessed by a mass, because of the gravitational field produced by a second mass.
Explanation:
Answer: magnitude and direction
Explanation:They are the two aspects of force that scientists measure
Answer:443.1 s
Explanation:
Given
Engine of a locomotive exerts a force of
Mass of train
Final speed (v)
F=ma
so
and acceleration is
Vertical forces:
There is a force of 579N acting upward, and a force of 579N
acting downward.
The vertical forces are balanced ... they add up to zero ...
so there's no vertical acceleration.
Not up, not down.
Horizontal forces:
There is a force of 487N acting to the left, and a force of 632N
acting to the right.
The net horizontal force is
(487-left + 632-right) - (632-right - 487-right) = 145N to the right.
The net force on the car is all to the right.
The car accelerates to the right.
