Abasketball has a mass of 609 g. moving to the right and heading downward at an angle of 32° to the vertical, it hits the floor with a speed of 3 m/s and bounces up with nearly the same speed, again moving to the right at an angle of 32° to the vertical. what was the momentum change ? (take the axis to be to the right and the axis to be up. express your answer in vector form.)

1.549 kg-m/s

Explanation:

Given

mass of basketball =609 g

ball is moving downward right at an angle of with vertical

After hitting the floor it moves with a speed of 3 m/s

change in Momentum in x direction

where u=3m/s

v=3m/s

m=mass of ball

Change in momentum in Y-direction

answer: cesare beccaria developed the classical school of criminology with from philosopher jeremy bentham

explanation:

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.
