Constants in the expression for force

Assignment Help Physics
Reference no: EM131436175

A hovercraft moves across a horizontal ice sheet described by the xy plane. The craft and pilot have a mass of 358 kg. At the instant that a strong wind begins to blow, the hovercraft has a velocity ?v= 4 m/s (^i)+6.25 m/s (^j) The wind applies a force given by F= 208 + 49.5 t^3 at an angle of 235 degrees relative to +x. The force expression is in units of Newtons when time in measured in seconds.

a. What are the units of each of the constants in the expression for force?

b. Calculate the displacement of the hovercraft from the instant that the wind begins to blow until it reaches a zero velocity in the y direction.
