Suppose that she pushes on the sphere tangent to its surface with a steady force of F = 25 N and that the pressured water provides a frictionless support. Calculate the angular acceleration of the sphere.
Express your answer to two significant figures
Moi of sphere is 1600kgm^2
Radius = 90cm
Mass= 4900kg

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
