Spin It!
• τ=F·r F=m·a
• m= 0.032 slugs
• r= 0.167 ft
• The acceleration was found by constant acceleration equation:
• d is the distance the ball travels which is 1.417 ft.
• V2= 4.79 ft/s V1= 0 ft/s
• (4.79 ft/s)2= (0 ft/s)2 + 2a(1.417 ft)
• a= 8.13 ft/s2
• F= (0.032 slugs) (8.13 ft/s2) = 0.026 lb
• τ = (0.167 ft)(0.026 lb)= 0.0043 ft-lb
The POP
• mgh = ½mV2
• mass cancels out in the calculation
• g= 32.2 ft/s2
• h= 0.875 ft
• (32.2 ft/s2)(0.0875 ft)= ½V2
• V= 7.51 ft/s
Ball Drop
• mpd+mbd/mp+mb
• (.00014slugs)(1.29ft)+(.0013slugs)(.75ft)/(.00014slugs)+(.0013slugs)
• Center of mass=0.88ft from tied side
• V1= 0 ft/s
• a= 32.2 ft/s2
• d=1.29 ft
• v22=(0 ft/s) + 2(32.2 ft/s2)(1.29 ft)
• V2= 9.11 ft/s
• X: V1 (found with conservation of energy)= 1.036 ft/s
• V2= 0 ft/s
• d= 0.083 ft
• a= -6.47 ft/s2

.

Final Step

Perfectly inelastic collision

mball (Vball) + mcup(Vcup)= (mball+mcup)Vfinal

mball=0.0015 slugs

Vball=9.11 ft/s

mcup=9.01*10-4

Vcup=0 ft/s

(0.0015slugs)(9.11 ft/s)+0=(0.0024 slugs) Vfinal

Vfinal= 5.69 ft/s

Issues
• Initial Ramp
• Hitting the cup reliably
• Popping the balloon (placement of needle)
• Working out minor kinks
