Answer:
vertical velocity = 33.55 m/s
Explanation:
sin (34) = v/60
sin (34) x 60 = v
33.55 m/s = v
Answer:
The elastic potential energy PE=143.47kJ
Explanation:
This problem bothers on the potential energy stored in a material.
Given data
Mass of the bungee jumper
m= 75kg
Height of jump down the cliff h=195m
We know that the elastic potential energy stored is same as the potential energy of the bungee jumper
PE= 1/2kx²= mgh
Assuming g is 9.81m/s²
PE= 75*9.81*195
PE= 143471.25J
PE=143.47kJ
What is potential energy?
Potential energy is the energy possessed by a body by virtue of it position.
Use the formula
E=h.lambda
Answer:
2.52N
Explanation:
according to law of moments ,
F1L1=F2L2 ,where the forces are in equilibrium .
0.85(44.5)= 15F2
that is , taking their distances from 50cm point
37 .825=15F2
37.825÷15= F2
2.52N = F2
