- Imagine a small moon with a mass equal to 1.3 times the mass of the Earth's moon. How much work is done y this moon on a 1,331 kg meteor which comes from outer space and impacts the surface of the moon? You should assume that the radius of this moon is equal to the radius of Earth's moon. Where the radius of Earth's moon = 1,738 km.A man does 4,480 J of work in the process of pushing his 2.70 103 kg truck from rest to a speed of v, over a distance of 25.5 m. Neglecting friction between truck and road, determine the following. (a) the speed v (in m/s) m/s (b) the horizontal force exerted on the truck (in N) NA man does 4,570 J of work in the process of pushing his 2.40 103 kg truck from rest to a speed of v, over a distance of 27.0 m.
