Aprofessional golfer hits a golf ball of mass 46 g with her 5-iron, and the ball first strikes the ground 155 m away. the ball experiences a drag force of magnitude fr = cv^2 and has a terminal speed of 44.0 m/s. calculate the drag constant c for the golf ball.

Explanation:

It is given that,

Mass of the golf ball, m = 46 g = 0.046 kg

Terminal speed of the ball, v = 44 m/s

The drag force,

Where, C is the drag coefficient. At terminal speed, the weight of the ball is balanced by the drag force.

Hence, this is the required solution.

in physics zero. in muscle fatigue could be high

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
