A golfer gives a ball a maximum initial speed of 34.4 m/s (a) What is the longest possible hole-in-one shot for this golfer? Neglect any distance the ball might roll on the green and assume that the tee and the green are at the same level. (b) What is the minimum peed of the ball during this hole-in-one shot?

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

option number c is the right answer.
