Explanation:
From what I can see in the question, there is a monkey of mass m suspened at the end of a spring which constant is k and this monkey has moved a distance d.
The mechanical energy for the situation will be composed of elastic potential energy from the spring, kinetic energy from the monkey and potential gravitational energy from the monkey as well.

where m is the monkey's mass,
is the speed of the monkey, d is the distance that the monkey has moved, k is the spring constant and x is the distance that the spring has stretched
Energy = Fd = 4.5*9.81*1.5=66.21J
Answer:
85 K
Explanation:
T₀ = initial temperature of the gas = 77 K
T = final temperature of the gas = ?
n = number of moles of monoatomic gas = 1.00 mol
R = universal gas constant = 8.314
c = heat capacity at constant volume = (1.5) R = (1.5) (8.314) = 12.5
Q = Amount of heat absorbed = 100 J
Amount of heat absorbed is given as
Q = n c (T - T₀)
100 = (1) (12.5) (T - 77)
T = 85 K
