Answer:
He has a speed of 16.60m/s after 35.0 meters.
Explanation:
The final velocity can be determined by means of the equations for a Uniformly Accelerated Rectilinear Motion:
(1)
The acceleration can be found by means of Newton's second law:
Where 
is the net force, m is the mass and a is the acceleration.
(2)
All the forces can be easily represented in a free body diagram, as it is shown below.
Forces in the x axis:
(3)
Forces in the y axis:
(4)
Solving for the forces in the x axis:
Where 
and 
:
Replacing in equation (2) it is gotten:
So the acceleration for the cyclist is 
, now that the acceleration is known, equation (1) can be used:
However, since he was originally at rest its initial velocity will be zero (
).
He has a speed of 16.60m/s after 35.0 meters
Answer:
The velocity of the rocket is 7.8 m/s
Explanation:
Answer:
So do 2400 divided by 70. I got 34.285714 and the numbers behind the decimal are repeating. If you round it you get 34.3
Answer:
just divide 22 N by 20 kg to get the acceleration in m/s2
Explanation:
I hope this is right-
Answer:
Disruption to electricity power grid
Explanation:
We're looking a a solar flare. This will whip solar particles at high velocity into space and, If they are near earth, will interact with the earth's magnetic field. These magnetic changes will be measurable in the electric grid. Whether they are strong enough to cause "disruption" depends on a huge number of factors such as strength of and angles of the interacting magnetic fields and location of grid infrastructure,
