A 100kg person climbs a 170 cm flight of stair in 1.4 second find the work done to climb the stairs and the power of the person in watts.
A person lives on the third floor of a building and he runs up the stairs three times a day. Each floor has 24 steps and height of each step is 15 cm. a) If the person weight is 65 kg calculate how much energy he uses each day. b) If he runs from first floor to the third floor in 20 seconds, calculate the person power output
Two people respectively 100kg and 70kg, are standing on a bridge
100m above water. They are attached to an bungee cable with
coefficient of k=3 kN/m. Find Initial length of the cable if its
max length is when the people touch the water. Height of people is
negligible. Found L initial to be 10.54m. Now I must find the
height person 2 (70kg) will reach on the way back up if person one
(100kg) were to let go when max...
