A 95-rm m-long train begins uniform acceleration from rest., Ask an Expert

Academics

Q. Cart is propelled over a xy plane with acceleration components ax = 4.5 m/s2 and ay = -2.0 m/s2. Its initial velocity has components v0x = 8.0 m/s and v0y = 13 m/s. In unit-vector notation, what is the velocity of the cart while it reaches its greatest y coordinate?

Q. A 95-{rm m}-long train begins uniform acceleration from rest. The front of the train has a speed of 25 {rm m/s} when it passes a railway worker who is standing 120m from where the front of the train started. What would be the speed of last car as it passes the worker?
