In order to convert a tough split in bowling, it is necessary to strike the pin a glancing blow as shown in the figure. Assume that the bowling ball, initially traveling at 15.0 m/s, has eight times the mass of a pin and that the pin goes off at 75° from the original...
For b) Find the time. There are two parts because one half of the parabola has a different floor height.
vinitialx=vinitialsin(θ)
vfinal=vinitial+at
tup=-vinitial/g
vfinal2=vinitial2+2ad
(d+5)=1/2at2
tdown=√[2(d+5)/g]
tup+tdown=ttotal
The horizontal component maintains a constant...
