Solve the all parts of given question:
Question: The acceleration of a bus is given by ax(t)=αt, where α = 1.28m/s3 is a constant.
Part I: If the bus's velocity at time t1 = 1.13s is 5.09m/s, what is its velocity at time t2 = 2.02s?
Part II: If the bus's position at time t1 = 1.13s is 5.92m, what is its position at time t2 = 2.02s?
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 for above question!
