Answer:
The average velocity for the time period beginning when t=1 and lasting 0.1 seconds = 16.40 ft/s.
Explanation:
Given that the height of the ball at time t is
The average velocity of an object is defined as the total displacement covered by the particle divided by the total time taken in covering that displacement.
If are the heights of the ball at time
and
, then the total displacement covered by the ball from time
to
is
.
Thus, the average velocity of the ball for the time interval is given by
For the time interval, beginning when t = 1 second and lasting 0.1 seconds,

Answer:
a
b
Explanation:
Now looking at the diagram let take that the magnetic field is moving in the x-axis
Now the magnetic force is mathematically represented as
x B
Note (The x is showing cross product )
Note the force(y-axis) is perpendicular to the field direction (x-axis)
Now when the loop is swinging forward
The motion of the loop is from y to z to to x to y
Now since the force is perpendicular to the motion(velocity) of the loop
Hence the force would be from z to y and back to z
and from lenze law the induce current opposes the force so the direction will be from y to z to x
Now when the loop is swinging backward
The motion of the induced current will now be x to z to y
