Concept explainers
a.
The velocity and acceleration at the top.
a.
Answer to Problem 45PP
At the top velocity
Explanation of Solution
Given:
Acceleration
Formula Used:
v is the final velocity
u is the initial velocity
t is the time
s is the distance
a is the acceleration.
Calculation:
At the top of the trajectory the coin is at rest, hence the velocity is
As the coin is flipped it is constantly under the influence of the gravity, hence at the top of the projectile acceleration
Conclusion:
At the top velocity
b.
The initial velocity.
b.
Answer to Problem 45PP
Explanation of Solution
Given:
Final velocity
Distance travelled
Formula Used:
v is the final velocity
u is the initial velocity
t is the time
s is the distance
a is the acceleration.
Calculation:
Substituting the values
Conclusion:
The initial velocity of the coin
c.
The total time taken in the flip.
c.
Answer to Problem 45PP
The total time taken in the flip is
Explanation of Solution
Given:
Final velocity
The initial velocity of the coin
Distance travelled
Formula Used:
v is the final velocity
u is the initial velocity
t is the time
a is the acceleration.
Calculation:
Calculation the time taken to reach the highest point.
Substituting the values
The total time is twice the time taken to reach the highest point.
Total time is
Conclusion:
The total time taken in the flip is

- Two-point charges of 5.00 µC and -3.00 µC are placed 0.250 m apart.a) What is the electric force on each charge? Include strength and direction and a sketch.b) What would be the magnitude of the force if both charges are positive? How about the direction? c) What will happen to the electric force on each piece of charge if they are moved twice as far apart?
