Answer:
The student will swing to a height of 61.25 cm.
Explanation:
Given that,
Mass of the student, m = 80 kg
Speed of student, v = 3.5 m/s
The student running at this speed grabs a rope that is hanging vertically. In the whole process, the energy of the system remains conserved. So, using conservation of energy to find the height reached by the student. So,
h is height reached by the student
So, the student will swing to a height of 61.25 cm.
