While playing basketball in PE class, Logan lost his balance after making a lay-up and colliding with the padded wall behind the basket. His 70-kg body decelerated from 10 m/s to 0 m/s in 0.20 seconds. a. Determine the force acting upon Logan's body.
b. If Logan had hit the concrete wall moving at the same speed, his momentum would have been reduced to zero in 0.0070 seconds. Determine what the force on his body would have been for such an abrupt collision

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

Who was the first scientist to measure speed as distance over time?

How can you improve the percent yield of copper in this lab? check all possible strategies that will you do so. measure reactants precisely. stir to the reaction take place. chill the reactants before combining them. wait patiently until the reaction completes. make sure to recover as much copper as possible.
