Answer:
F = 960 N
Explanation:
given,
acceleration = 2 m/s²
Force = 450 N
mass = 255 Kg
to calculate the force propelling the bobsled forward
∑ F = ma
F - f = ma
F = m a + f
F = 255 × 2 + 450
F = 510 + 450
F = 960 N
the magnitude of the force propelling the bobsled forward is F = 960 N
Answer:
That is related to the fact that our numbering system - the decimal system - is based on powers of 10.
Explanation:
As described above, the acceleration of the object is given by the equation, a=2d/t^2. If the object accelerates at a distance of 15 meters, then it can be said that the acceleration will be doubled as compared to the previous with the same time squared. Time can be related by the equation,
t=sqrt of 30/a

Explanation:
Answer:
55,42 J
Explanation:
Since the height of the room is 3.45 m (distance between the floor and the ceiling) the difference between this value and the length of the rope 1.19 m; it will be equal to (3.45-1.19) =2.26 m. If we take as a reference point (Ep=0) the floor of the room, then the potential energy will be equal to Ep = M * g * h, replacing values in this equation (2.5 kg * 9.81 m/s2 * 2.26 m) will be 55,42 (N * m) or Jules.
