A spaceship has two engines oriented perpendicularly (inxandydirections). The ship is initially at rest. One engine fires and gives the rocket an accelerationax = 5 m/s2. At the same time, the other engine fires and gives the rocket an accelerationay = 3 m/s2. The rocket oriented in thexdirection fires for 5 s and the rocket oriented in theydirection fires for 10 s. How far does the ship travel in theydirection in 10 s? Show all of your work.
Two packing crates of masses m1 =10.0 kg and m2 = 6.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below.The 6.00 kg crate lies on asmooth incline of angle 45.0°. Find the acceleration of the 6.00 kg ..
