Aparticle starts from s=0 and travels along a straight line with v=(t^2 - 4t + 3) m/s, where t is in seconds. construct the v-t and a-t graphs for the time interval 0< =t< =4s.

How much work is done lifting a 9.10 kg box straight up onto a shelf that is 1.80 m high?

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
