A football quarterback runs 13 m straight down the playing field in 2.2 s (in the positive direction). He is then hit and pushed 2.5 m straight backwards in 1.8 s. He breaks the tackle and runs straight forward another 23 m in 4.8 s. show answer No Attempt 25% Part (a) Calculate the quarterback's average velocity in the horizontal direction during the first interval, in meters per second.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

Choose each of the settings that follow and list them below do it ill mark brainliest first object= position= speed= acceleration= second object= position= speed= acceleration=
