A friction-free simple pendulum has a speed of 1.24 m/s when at its lowest point in its motion. How high will the bob get (compared to the lowest position) when it is at rest during its motion

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.
