Solve the following question given below:
Question: Two objects begin at different corners of an equilateral triangle with sides of length 32 m and race towards the third corner. The first object begins at rest at t = 0 and accelerates at a constant rate of 4 m/s2. If the second object makes the trip at a constant speed of 40 m/s, how long after the first object begins should the second object start so that they meet at the final corner at the same time?
For some reason I keep getting it wrong I don't know if it's a calculation error. Please show your work so I can see what I'm doing wrong with this question!
