The average speed is 40m/s
according to the research i did on the net a worm travels a distance of 40m in 20 minutes. you would calculate the average speed of the worm in m/minute.
Work = (force) x (distance). Work = (20N) x (40m) = 800 N-m = 800 J. Since we're given the force and the distance, we don't need the weight of the cart.
The short answer is 28 m/s. Here is how you come to this. There is a basic physics formula you use to determine the distance something has traveled, using your initial distance/position, initial velocity, acceleration and time. This formula is: x = x0 + v0t + 1/2at^2 (x0 is x-naught, the initial distance, v0 is v-naught, the initial velocity. The zero should be a subscript). The formula for it's velocity is simply the first derivative of the distance formula, which is: v = v0 + at To find the velocity it is at after it has traveled 40m, we first need to know the time it took to fall 40m, so we can make use of our distance formula. We know that we have traveled 40m, so we use that for x. We can say our initial position is 0m and our initial velocity is 0m/s. Our acceleration is that of gravity, which is 9.8m/s/s. We plug these in and solve for t: 40 = 0 + 0t + 1/2(9.8)t^2 40 = 4.9t^2 t = sqrt(40/4.9) = approximately 2.86 Then, we just use that time and the same acceleration and plug them into our velocity formula: v = 0 + 9.8(2.86) v = 9.8(2.86) v = 28 m/s (It's exactly 28 m/s if you use the exact value for t)
Distance is a scalar quantity; it only gives you the value.Displacement is a vector quantity; it gives you the value and the direction.Example of distance - point A is 40m from point CExample of displacement - Point A is 40m from Point C, in a western direction.
The average speed is 40m/s
Displacement is just distance traveled and a direction. For example 40m east is a displacement distance
40m in 20 minutes 120m in 60 minutes or 1 hour 0.12km in 1 hour
40m long by 20 wide
6h 40m duration, 1+ stops
1,000,000,000,000s = 16,666,666,666m, 40s = 277,777,777h, 40m, 40s = 11,574,074d, 1h, 40m, 40s = 31,688y, 32d, 1h, 40m, 40s So assuming all that math is correct, one trillion seconds is about 31,688 years.
To calculate the volume of a rectangular prism, you multiply the length, width, and height. 40m × 40m × 60m = 96, 000 m3.

Interval training is quite effective to develop Anaerobic Capacity. Working over a distance of maybe 60/80m with a active rest (walking) of 20seconds is a good place to start. To make it harder, increase the distance of the sprints and decrease the rest period. Pyramid training will also help. *Sprint 20m have a 10 second break *Sprint 40m have a 15 second break *Sprint 60m have a 15 second break *Sprint 80m have a 20 second break *Sprint 60m *Sprint 40m *Sprint 20m
1600, equal 40m*40m
0.0254 m = 1 in (exactly) → 40m = 40 ÷ 0.0254 in ≈ 1574.8 in
