1. a golf ball rolls up a hill toward a miniature-golf hole. assume that the direction toward the
hole is positive.
a. if the golf ball starts with a speed of 2.0 m/s and slows at a constant rate of 0.50 m/s, what is
its velocity after 2.0 s?
b. what is the golf ball's velocity if the constant acceleration continues for 6.0 s?

whichever one it is, it's definitely not one that you included on the list you provided.

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.
