A rocket is attached to a person in a sled with a combined mass of 55 kg. The sled is launched with 360 N of thrust up a frictionless icy hill sloped at 19° from the horizontal. What is the magnitude of acceleration of the sled while it travels up the hill?

weight = 55 g = 55*9.81 = 540 Newyons
component of weight down slide = 540 sin 19 = 176 N
so net force up slope = 360 - 176 = 184 N
a = 184/55 m/s^2
