An object moves 114m [W] in 3.0s while accelerating at a constant 8.0m/s^2 [E].
a) Determine the initial velocity (50 m/s [W])
b) Determine the final velocity (26 m/s [W])

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 .
