A student is late and running to class. A hall monitor tells them to slow down, so the student slows to a walking speed of 1.4 m/s. It takes the student 3.0 seconds to slow to this speed, due to the student’s -2.5 m/s2 acceleration. What was the student’s initial speed

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
