In a slap shot, a hockey player accelerates the puck from a velocity of 6.00 m/s to 40.0 m/s in the same direction. if this takes 3.33 ✕ 10−2 s, calculate the distance over which the puck accelerates.

0.766 m

Explanation:

initial velocity of puck, u = 6 m/s

final velocity of puck, v = 40 m/s

time taken by the puck, t = 3.33 x 10^-2 s

Let the acceleration of puck is a and the distance traveled by the puck is s in the given time.

Use first equation of motion

a = 1021.02 m/s^2

Now to find the distance, use third equation of motion

s = 0.766 m

Thus, the distance traveled by the puck is 0.766 m.

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.

explanation:

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
