Question

Detailed explanations please?

A golfer located at (0.0) hits a golf ball towards a hole located at (x0, 0) with speed V0 at ail angle pi/4 with respect to the horizontal. As the ball travels in the air. a man with a radar gun measures the speed of the golf ball at some height equal to . The shot was a hole-in-one. Determine X0 and the total time of flight tT. Determine the possible times t1 and t2 at which the golf ball was measured. Determine the height h at which the the golf ball was measured. Your answers should be in terms of vo. Show that g = 8h/t2T-t21rightarrow where t1 rightarrow 2 is defined as t2 - t1 where t2 > t1.

Explanation / Answer

a) xo=R=u^2sin2*45/g

=vo^2/g
t=2usin45/g

sqrt(2)vo/g
b)v=(vo^/2+vy^2)^.5

vy=vo/2sqrt(2)

vo/2sqrt(2)=vo/sqrt(2)-gt

t1=vo/2sqrt(2)g

t2=vo/sqrt(2)g+vo/2sqrt(2)g

=3vo/2sqrt(2)g

c)h=vo/sqrt(2)*vo/2sqrt(2)g-.5g*vo^2/8

.1875vo^2/g

d)Put the value of h,t1,t2 in above equation u will get g.
