Answer:
Fx = -7042.86N (Taking the right as positive sense of motion)
Fy = 2154.29N.
Explanation:
The full solution can be found in the attachment below. The approach to the solution involves the summation of the respective components of the momentum along the horizontal and vertical axis.
To the right is taken as positive sense of motion and the left as negative sense of motion.
The basic statement of Newtown's second law have been used which is
M(v2 – v1) = Ft
See the attachment below for the complete calculation procedure.
Answer:
Magnetism is a physical phenomenon that manifests itself in a force acting between magnets or other magnetized or magnetisable objects, and a force acting on moving electric charges, such as in current-carrying cables. The force action takes place by means of a magnetic field, which is generated by the objects themselves or otherwise. There are natural and artificial magnets. All magnets have two poles called the north pole and the south pole. The north pole of one magnet repels the north pole of another magnet and attracts the south pole of another magnet; the same with south poles.
On Earth, the acceleration due to gravity is (-9.8 meters per second) per second.
If the school, the roof, and the pencil are on Earth,
then after 3 seconds, the pencil's speed is
[ (-9.8 meters per second)/second ] times [ 3seconds ] = <u>-29.4 meters per second </u>
Answer:
62.6 m/s down
Explanation:
Taking downward to be positive:
Given:
v₀ = 0 m/s
Δy = 200 m
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (200 m)
v = 62.6 m/s
