Explanation:
Detailed explanation-1: -C) Use the maximum height formula to determine the initial velocity for launching the golf ball, so that the maximum height reached equals 5.2 meters, assuming that the launch angle is 30 degrees.
Detailed explanation-2: -Updated On: 27-06-2022 The correct Answer is 20 m. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. A ball thrown vertically upwards returns to the thrower in 20 second. Calculate the velocity with which it was thrown and the maximum height attained by the ball.
Detailed explanation-3: -It goes to a height of 20 m and then returns to the ground. Taking acceleration due to gravity g to be 10 m/s2 .
