The crazed physics student's lab partner decides to throw another pumpkin off the roof with an initial velocity of 19.4 m/s. What is the velocity when the pumpkin strikes the ground if it takes 3.2 seconds for it to fall?

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.
