if p=7i+3j+2k and q=4i+5j-3k. find the (i)cosine angle between p and q,(ii)magnitude of p,(iii)magnitude of q,(iv)the scaler product of p. q please show your solving thanks

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

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
