A snowboarder on a slope starts from rest and reaches a speed of 4.0 m/s after 9.1 s. (a) What is the magnitude of the snowboarder's average acceleration

where are the vectors ?

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

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

answer( sicar );
