How do you get average velocity for simple problems?
In the simplest case, you divide the distance travelled (directed distance, if you want a velocity as opposed to a speed) by the time it takes. Read More »

What is the average velocity of this problem?
Remember that average velocity is Total distance travelled divided by Total time travelled. Total time travelled is easy; that's 9 seconds. The distance travelled can be computed by finding the area under the velocity-time curve as follows:... Read More »

This kind of question is tricky, because average velocity is not simply the average OF the velocities. The reason is you spend more time driving the slower part. The correct approach is to compute (average velocity) = (total distance) / (to...

I presume that you know the formula s = ut + ½at² ? You have u = 0, s = 800 m, and you want to find a such that t > 20 sec. Or, in other words, for t = 20 sec. or less, s must be greater than 800 m. So, 800 > 0(t) + ½ a 20² 800 / (½20²) > a...

find the velocity function: v= ds/dt = t+1/2 average of a continuous function = Integral( v dt)/Integral(dt) between t=0 and t=40 the numerator becomes t^2/2 + 1/2 t evaluated at t=4 and t=0 (at t=0, the funciton =0)' the denominator is sim...

Since the car spends equal time at the two speeds it is legitimate to just average the two speeds. The average of 50 and 66 is 58 km/h, the average speed. **Remember that you can only use this simplified method when the object spends equal ...

Let S, V & T represent distance, velocity and time S = V*T so total distance traveled = 3*97 + 3* 72 = 507 km Total time traveled = 3 + 3 = 6 hrs Thus average velocity = S/T =507/6 = 84.5 km/hr Ans: 84.5 km/hr, 85 km/hr if rounded off
