What is the de broglie wavelength of a 149-g baseball traveling at 95.4 mph? (1 mile = 1.609 km, h = 6.63 × 10–34 j·s)?
boyakko [2]

The solution for the problem is:

Wavelength = Planck’s constant/(mass*velocity) 

Planck’s constant= 6.63*10^-34 with units of J-s or kg-m^2/s^2-s 

mass = 149g = 0.149 kg 

velocity = 95.4.mi/1hr(1609.3m/1mi)(1hr/3600sec) = 42.65m/s 

h/mv = 6.63*10^-34 kg-m^2/s^2-s/(42.65m/s*0.149kg)

wavelength = 1.04 *10^-34 m

Leroy who has a mass of 100kg, is skateboarding at 9.0 m/s when he smacks into a brick wall and comes to a dead stop at 2.0 s
gtnhenbr [62]
F = m*a
a = v/t
a = 9.0 m/s / 2.0 s
a = 4.5 m/s^2
F = 100 kg * 4.5 m/s^2
F = 450 N
Sig figs = 500 N?

A rope pulls on a metal box at an angle of 60.0° with a force of 255 N. The box moves horizontally for 15.0 m. How much work was
Iteru [2.4K]
The work done by the rope on the box is equal to:
W=Fd \cos \theta
where F is the force applied by the rope, d the  distance covered by the box and \theta is the angle between the direction of the force and of the displacement.

Using the data of the problem: F=255 N, d=15.0 m and \theta = 60^{\circ}, we find the work:
W=(255 N)(15.0 m)(\cos 60^{\circ})=1912.5 J
