mathematical expression of velocity. Consider the following methodological remark. Using the results in Questions 5 and 6 compute the average velocity on the interval.
Notice that now a is a constant in time. A projectile is an object that we give an initial velocity and gravity acts on it. When talking about velocity we specify it according to some fixed frame of reference and its unit is meterssecond.
Hence the formula for velocity can be expressed as.
1632 v l T l T 2 p 2 p o k. 20 ms to the south. To put it simply speed is the magnitude of velocity. Notice that now a is a constant in time.
