A tennis ball is shot straight up with an initial velocity of 28 m/s (Use g= -10m/s/s) Calculate the maximum height of this projectile:
meters

Calculate the velocity of this object after 2 seconds:
meter/second

Calculate the height of this object after 2 seconds:
meters

Vertical Dimension (Y-axis) of Motion

Horizontal Dimension (x-axis) Motion

A negative acceleration occurs due to the net force of gravity

Constant Motion as there is no net horizontal forc

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
