A tiger started running when it saw a deer running at uniform velocity 2m/s at 15m far from it ..if the tiger ran at acceleratio
Masteriza [31]
You need to set their position functions equal to one another and so for the time t when that is true. That is when the tiger and the deer are in the same place meaning the tiger catches the dear
Xdear= 2t+15 deer position function.
(I integrated the velocity function )
To get the Tigers position function you must integrate the acceleration twice. This becomes
Xtiger=t^2
Now t^2=2t+15
Time t is when the tiger catches the deer
t^2-2t-15=0
(t-5)(t+3)=0 factored
t=5s is the answer you use (t=-3 is a meaningless solution)

Anyone know 1-5? Will give brainliest
baherus [9]

Answer:

1. 200 metres West

2. Dividing distance by time

3. Speed was unchanged

4. 1800 metres

5. 15 seconds

Explanation:

Running 500 metres West puts you 500 Metres west from the start. Then running 300 metres east puts you 200metres from where you started.

Since displacement is the distance you are from your original position 200 Metres West is the answer

2. Distance = Speed x Time

Rearrange that to get Speed = Distance / Time

3. Acceleration is when the rate of increase or decrease of speed or the direction is changing. When the speed or sirection dont change acceleration is 0

4. Distance = Speed x Time

60 x 30 = 1800 metres

5. Time = Distance / Speed

300 / 20 = 15 seconds
