Answer:
33.33 seconds
Explanation:
= Initial length pulled = 20 cm
b = Damping constant = 0.015 kg/s
k = Spring constant = 4 N/m
m = Mass of glider = 250 g
Time period is given by
Using exponential decay formula
Final amplitude = Initial times decay
The time taken is 33.33 seconds
Can you give more description ??
Answer:
The coefficient of friction in the hall is 0.038
Explanation:
Given;
mass of the Parker, m = 73.2 kg
applied force on the parker, F = 123 N
frictional force, Fs = 27.4 N
the coefficient of friction in the hall = ?
frictional force is given by;
Fs = μN
Where;
μ is the coefficient of friction
N is normal reaction = mg
Fs = μmg
μ = Fs / mg
μ = (27.4) / (73.2 x 9.8)
μ = 0.038
Therefore, the coefficient of friction in the hall is 0.038
Your car is performing a transformation of energy of:
Chemical energy to Mechanical energy
The chemical is the gasoline which is then converted to fire as the car runs thus creating the movement of the car which is mechanical energy.
If you give us the situation described then I'll be able to help.
