What have helped this boy is doing more treatments scud
This is my notes from last year my teacher really dumbed it down for us lol and it really helped but I'm not so sure if ur question would be answer with this but ik it will help with other problems for Physics I just thought I would share it I hope this helps have a lovely nite and good luck with this question let me know if the pics are good or not!
Answer:
14,653 J.
Explanation:
We know that,
Total mechanical energy is equal to the sum of all the potential and kinetic energies.
Given,
Kinetic energy when a car jumps off a ramp= 5000 J
Potential energy = 4685 J
Potential energy when the car lands= 4968 J
TME = 5000 + 4685 + 4968
= 14,653 J
Hence, the car's total mechanical engery is equal to 14,653 J.
The mass that must be added is 0.628 kg
Explanation:
The period of a mass-spring system is given by

where
m is the mass
k is the spring constant
For the initial mass-spring system in the problem, we have
m = 0.500 kg
T = 1.36 s
Solving for k, we find the spring constant:

In the second part, we want the period of the same system to be
T = 2.04 s
Therefore, the mass on the spring in this case must be

Therefore, the mass that must be added is
