A man-made satellite orbits the earth in a circular orbit that has a radius of 10000 km. The mass of the Earth is 5.97e+24 kg. What is the tangential speed of the satellite?

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
