Will a body moving in a circular track have zero acceleration? Vividly explain your making reference to both radial and perpendicular acceleration? EV (7)
b) In your own words describe first moment of area for any shape and its importance. With reference to the shape below about the axis s – s, describe the position of the centroid.

c) In quantum mechanics, the fundamental constant called Planck’s constant, h, has dimensions of ML2T−1 . Construct a quantity with the dimensions of length from h, a mass m, and c, the speed of light.

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

real, smaller and upside-down.   so the answer should be b.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
