A 2500 kg satellite is flying through empty space at speed vi = 20km/s. Find the change in its speed after an impulse J = 5 * 10^6 N is applied a, if J is directed along vi, and if J is perpendicular to vi.
A speedboat increases its speed uniformly from vi = 20.0 m/s to vf = 29.0 m/s in a distance of Δx = 1.60 ✕ 102 m. (a) Draw a coordinate system for this situation and label the relevant quantities, including vectors. A speedboat in two positions is shown. The speedboat on the left has a speed vi with its vector pointing to the right. The speedboat on the right is at a distance of Δx (in meters) from the speedboat...
