Two students were responsible for recording the velocity of a rocket that blasted from ground zero. Student A recorded the final velocity at 4,680 ft/min. Student B was responsible for recording the initial velocity after thrust burnout which was 900 km/sec. What would be the acceleration of this rocket in m/s2, if the total amount of flight was 980 seconds? What is the acceleration from problem 1 in mph?

A car accident happened on the corner of 42nd and Grandview. A police officer measured the skid line of the truck involved. It measured to be 536 ft. A camera caught the truck stopping in 7 sec. Determine how fast the truck was traveling in miles/hr.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

No. rocks can follow various pathways.
