A 0.16 kg hockey puck is moving on an icy horizontal surface with a velocity of 8 m/s. A player strikes the puck with a hockey stick, after the impact the puck moves in opposite direction with a velocity of -15 m/s. If the puck was in contact with the stick for 0.005 s, what is the average force on the puck by the stick

Alice added sodium chloride to water and stirred the water for several minutes. alice is most likely trying to demonstrate that ionic compounds a. are hard. b. can dissolve. c. are clear. d. can melt.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
