Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?

You fire a bullet into a 3 kg wooden block attached to a spring with spring constant 70 n/m. when the bullet strikes the block, the spring compresses. the bullet has a mass of 0.03 kg and strikes the block with a speed of 200 m/s. what is the speed of the block and bullet when they first start moving together?

What is the difference between distance and displacement? give an example of a situation where distance and displacement both have the same magnitude. give another example, where distance and displacement have different values. make sure to address the terms "vector" and "scalar" in your response.
