I believe that if you multiply 120 x 45 you would get 5,400 why? Because when a problem has "of" means to multiply.
So... the vacuum cleaner is 5,400 percent efficient :)
Sorry if it's wrong I'm only in fifth grade
Answer:
a = (V2 - V1) / t for uniform acceleration
t = (20 - 15/ m/s / 2 m/s^2 = 2.5 s
S = V1 t + 1/2 a t^2 distance covered
S = 15 * 2.5 + 2 / 2 * 2.5^2 = 37.5 + 2.5*2
S = 37.5 + 6.25 = 43.75 m
i am 2.5 with the thhe 2020 is 3 and 5 is 7
The answer for question 2 i guess it’s c
