The picture attached shows the calculation
156 is the answer. so 156.25 is almost the same thing, you just round. It's not hard. Thank you!!!
there many things you could do, one is try getting a cooling system, another thing is its extramly hot and you may need to tunr off your car to prevent the engine from over heating.
Answer:
m = 4.29 kg
Explanation:
Given that,
Mass of the object, m = 2.8 kg
Stretching in the spring, x = 0.018 m
Frequency of vibration, f = 3 Hz
Let m is the mass of the object that is attached to the spring. When it is attached the gravitational force is balanced by the force on spring. It is given by :



k = 1524.44 N/m
Since, 


m = 4.29 kg
So, the mass that is attached to this spring is 4.29 kg. Hence, this is the required solution.
