Answer:
0.384c
Explanation:
To find the speed of the pursuit ship relative to the cruiser you use the following relativistic equation:
![u'=\frac{u-v}{1-\frac{uv}{c^2}}](https://tex.z-dn.net/?f=u%27%3D%5Cfrac%7Bu-v%7D%7B1-%5Cfrac%7Buv%7D%7Bc%5E2%7D%7D)
u': relative speed
u: speed of the pursuit ship = 0.8c
v: speed of the cruiser = 0.6c
c: speed of light
You replace the values of the parameters to obtain u':
![u'=\frac{0.8c-0.6c}{1-\frac{(0.6c)(0.8c)}{c^2}}=0.384c](https://tex.z-dn.net/?f=u%27%3D%5Cfrac%7B0.8c-0.6c%7D%7B1-%5Cfrac%7B%280.6c%29%280.8c%29%7D%7Bc%5E2%7D%7D%3D0.384c)
Hence, the relative speed is 0.384c

I belive this is the answer sorry if im wrong!
Answer:
You are given that the mass of the clock M is 95 kg.
This is true whether the clock is in motion or not.
Fs is the frictional force required to keep the clock from moving.
Thus Fk = uk W = uk M g the force required to move clock at constant speed. (the kinetic frictional force)
uk = 560 N / 931 N = .644 since the weight of the clock is 931 N (95 * 9.8)
us is the frictional force requited to start the clock moving
us = static frictional force = 650 / 931 -= .698
