The relationship between the weight and mass of an object is given by the formula, w=mg, where w=weight, m= mass and g= the strength of gravity. on the moon, the strength of gravity is 1.6n/kg. a 22-kilogram rock on the moon would weigh ?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
