An astronaut in deep outer space, away from the gravitational pull of any planets, puts a force on his wrench, which has a mass of 0.8kg. The wrench accelerates at a rate of 5m/s^2. What was the amount of force, in Newton’s, put on the wrench?

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 .
