Two blocks are connected by a rope, as shown below. The masses of the blocks are 10kg for the lower block and 5kg for the upper block . An upward applied force of magnitude F acts on the upper block. If F = 450N which of the following predictions about the acceleration of the two block system is correct?
1) The system accelerates downward with a magnitude 2g
2) The system accelerates downward with a magnitude 3g
3) The system accelerates upward with a magnitude 2g
4) The system accelerates upward with a magnitude 3g

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

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 .
