WebBe careful about which is which. If you are careful not to mix up the final and initial quantities, your answer will make sense. By the way, scalars can be negative. The mere fact that Δ t is a scalar doesn't mean it has to be positive. However, usually we say that final is later than initial, t f > t i, and that's why Δ t is usually positive. WebYes, it is possible to have negative velocity when acceleration is positive. Consider a body or an object moving in a negative direction, having a negative velocity and …
