Webb26 maj 2024 · Average Velocity (v)= S 2 – S 1 / T 2 – T 1 = S/T. Question 2: A Body at rest was accelerated, and it traveled for 5 minutes. The constant acceleration provided to the body was 2 m/sec 2. Find the final velocity the object had before coming to a stop. Also, answer the equation of motion used to find out the final velocity. Solution: WebbAnd so now we know the exact, we know the exact expression that defines velocity as a function of time. V of t, v of t is equal to t, t plus negative 6 or, t minus 6. And we can verify that. The derivative of this with respect to time is just one. And when time is equal to 3, time minus 6 is indeed negative 3.
