Here is the tasks. We have e ballon flying from point A to point B. We have x-axis and y-axis. x=2t and y=x(power 2) / 30. t=2 seconds. I have to calculate the distance between A and B after 2 seconds. I have to calculate the magnitude and direction of velocity and acceleration. Can you help me to solve this problem? I know that i have to find the velosity along x-axis and velocity along y-axis. And then we use pithagor theorem and we find the velocity. Can you help me a little bit ? How to do that ?
