I'm trying to solve this displacement problem but I dont know where to even start. If you could please explain I would really appreciate it. My professor didn't teach and refuses to help.
The velocity (in meters/sec) of a particle moving along a straight line is given by $ v\, ( t ) =1 t^2 -4 t + 4 $, where $ t $ is measured in seconds. Answer the following questions given that the initial position$ \, \,s (0) =1 $.
What is the meter position of the particle at any given time $ t $ ?
What is the meter position of the body at time $ t=4 $?
What is the meter position of the particle at time $ t=7 $ ?
What is the displacement of the particle on the time interval $ 4 \leq t \leq 7 $ ?
