Weight refers to the force of gravity acting on a mass. we often calculate the weight of an object by multiplying its mass by the local acceleration due to gravity. the value of gravitational acceleration on the surface of mars is 0.377 times that on earth. if your mass is 85 kg, your weight on earth is 830 n (m × g = 85 kg × 9.8 m/s² = 830 n). what would be your approximate mass and weight on mars?

What is created when solids, liquids, an gases mix with one another

The slope of a velocity time graph over any interval of time gives the during that interval

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?
