Detailed explanation-1: -a. If the golf ball starts with a speed of 2.0 m/s and slows at a constant rate of 0.50 m/s², what is its velocity after 2.0 s? =-1.0 m/s c. Describe the motion of the golf ball in words and with a motion diagram.
Detailed explanation-2: -AI Recommended Answer: 2. Add time (2 seconds). 3. Divide the result by 2 to get the speed in m/s: 20 m/s.
Detailed explanation-3: -Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.
Detailed explanation-4: -The initial velocity is defined as the speed of the ball as it travels 2 feet after impact with the striker. The measurement is made by electronically timing the ball as it passes through a light source and ballistic screen separated by a fixed distance of about 6.283 feet.
Detailed explanation-5: -Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.
