Plss help kinetic energy can be calculated using the formula KE= 1/2 mv2, where m=mass and v=velocity. Calculate the kinetic energy of an object with a mass 5kg moving at a velocity of 4m/s.

(c) the diagram shows the first three shapes of a matchsticks arrangement.first shape = 3second shape = 5third shape = 7given m represents the number of matchstick used to arrange the n'th shape.(i) write a formula to represent the relation between m and n. express m as the subjectof the formula.(ii) 19 matchsticks are used to make the p'th shape. find the value of p.
