Alonzo sprints for 500 meters along a straight track during a race. After crossing the finish line, he to walks back along the t
2 answers:
Answer:
450 meters straight ahead
Explanation:
As we know that displacement is the total vector displacement of the object from initial point to final point
As here the Alonzo moves in a straight line during the finish line which is at distance of 500 m
so initial displacement is given as
now for cool down he again moves back 50 meter along the same track in backward direction
so it is given as
so we can say that total displacement will be
straight ahead

The acceleration of this car is equal to 5 .
<u>Given the following data:</u>
- Initial velocity = 0 m/s (assuming it's starting from rest).
- Final velocity = 10 m/s.
- Time = 2 seconds.
To determine the acceleration of this car:
<h3>How to calculate acceleration.</h3>In Science, the acceleration of an object is calculated by subtracting the initial velocity from its final velocity and dividing by the time.
Mathematically, acceleration is given by this formula:
<u>Where:</u>
- V is the final velocity.
- U is the initial velocity.
- is the time measured in seconds.
Substituting the given parameters into the formula, we have;
Acceleration, a = 5

Answer:
The angle between the electric field lines and the equipotential surface is 90 degree.
Explanation:
The equipotential surfaces are the surface on which the electric potential is same. The work done in moving a charge from one point to another on an equipotential surface is always zero.
The electric field lines are always perpendicular to the equipotential surface.
As
For equipotential surface, dV = 0 so
The dot product of two non zero vectors is zero, if they are perpendicular to each other.
