2. A car is initially traveling at 23 m/s when the driver steps down hard on the gas pedal resulting in an acceleration of 2.0 m/s2. How fast will the car be moving 3.0 seconds later?

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
