Suppose a 60.0-kg gymnast climbs a rope. (a) What is the tension in the rope if he climbs at a constant speed? (b) What is the tension in the rope if he accelerates upward at a rate of 1.50 m/s2?
Expert Solution
Step 1
If a gymnast climbs at a constant speed then his acceleration is zero.
So for the first part,
a=0
The equation of motion is given by,
T=mg
where T is the tension,
Putting the value,
T=60
T=588 N
