Homework Statement
The questions refer to the attached graph
Q1 - calculate the instantaneous velocity of the object at time 2.5s
Q2 - calculate the instantaneous velocity of the object at time 7.5s
Q3- calculate the average velocity over the time of 7.5s
Q4- Is the motion of the object uniform or non-uniform?
Homework Equations
Unsure
The Attempt at a Solution
ANS 1: At 2.5s the object has traveled 4m, I am asumeing this means that at this time the instantaneous velocity is 4m per 2.5 sec witch then needs to be written in ms or kph?
ANS 2: same theory as above?
ANS 3: At 7.5 seconds the object has traveled 18.5m, to find the average I assume I divide the distance by time? but does this give me average speed not velocity? :S
ANS 4: I am saying non-uniform because the graph is not straight so the velocity and varies over the time
