Hey ... guys can you please help me... A lorry is travelling with a velocity of 30 m/s came to rest in 5s .What is it acceleration?

The answer is 6 m/s^2.

Explanation:

by using the formula,

a = v-u/t

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
