Hi guys, Would really appreciate your thoughts on the question below. 1. The problem statement, all variables and given/known data An object moves in a straight line and its displacement s at time t is given by -6t6-4t4+2. What is the velocity of the object at time t=7? Give the answer to the nearest whole number. 3. The attempt at a solution I calculated the answer as being -610540. However, the question asks to give the answer to the nearest whole number and to me that seems absurd unless I have the wrong answer of course. Would really appreciate if someone could check my answer and let me know if it's correct or not. Thanks in advance.
