A particle's acceleration is described by the function ax =(10-t)m/s^2, where t is in s. Its initial conditions are x0 = 160m and v0x =0m/s at t =0s.
Part A At what time is the velocity again zero?
Part B What is the particle's position at that time?
When the space shuttle (mass of the shuttle=2*10^6kg) was at the outer limit of Earth's atmosphere (distance= 350km above Earth's surface), astronauts measured the gravitational force from Earth to be equal to 1.7*10^7 newtons. Find the gravitatio..
A cube of ice is taken from the freezer at -8.4^circ C and positioned in a 114 g aluminium calorimeter filled with 322g of water at room temperature of 20.0 C. The final situation is observed to be all water at 15.0C.
