Just here is a bicycle coming at the speed of 6 meters bungalow, passing the car from behind (2 / 2) the farthest distance between the two vehicles before catching up with the bicycle? 2. The speed of the vehicle when catching up with the bicycle?
1/2*3*t^2=6t
t(t-4)=0
t=4
6t-3/2*t^2=-3/2(t^2-4t)=-3/2(t-2)^2+6

- 3. If an object moving in a straight line with uniform velocity changes 6 m in the second second, and the displacement is 0 in the fifth, what is its initial velocity and acceleration? Let the direction of the initial velocity be the positive direction. I've previewed it, but some haven't learned it
- 4. When an object moves in a variable speed straight line, the distance it passes in the first second is 3M, the distance it passes in the second second is 5m, and the distance it passes in the first three seconds is 15m, then what is its average speed in the first second, the average speed in the first two seconds, and the average speed in the third seconds?

- 15. As for free falling bodies, why does falling time have nothing to do with mass In vacuum, two objects with the same volume but different mass. The one with larger mass bears more force. Why do they land at the same time as the one with smaller mass? Please talk about it in combination with the actual situation, The reason why it will fall is due to gravity, and the mass is related to gravity. How can the speed be the same? What's going on
