Answer:
a) It reduces the kinetic energy loss of the stunt person.
<span>A, The law of universal gravitation states that an increase in mass causes an increase in gravitational force. For this reason, the sun keeps all the planets in orbit because this classical and physical law describes the gravitational interaction between bodies.</span>
Answer:
The frequency of oscillations is 7 Hz
Explanation:
Given;
mass of car, = 1700 kg
mass of driver, = 66 kg
compression of the spring, x = 5mm = 0.005 m
The frequency of the oscillation is given as;
where;
k is force constant
m is the total mass of the car and the driver
m = 1700 kg + 66 kg = 1766 kg
Weight of the car and the driver;
W = mg
W = 1766 x 9.8
W = 17306.8 N
Apply hook's law, to determine the force constant;
F = kx
W = F
Thus, k = W/x
k = 17306.8 / 0.005
k = 3461360 N/m
Now, calculate the frequency
Therefore, the frequency of oscillations is 7 Hz
