(b) the maximum rate of change of the magnetic flux is given by:
(c)
(d) The torque is given by:
Answer:
The time depends on the distance that they have to travel
Explanation:
The only horizontal force exerts over the car and you, it is the force that your friend is applied
Newton's Second Law of Motion defines the relationship between acceleration, force, and mass, thus
550 = 1430a
a = 0.3846 m/s2
The car and you have a motion under constant acceleration, then theirs position to a time-based is:
By the initial conditions
The time depends on the distance that they have to travel
