A296-kg motorcycle is accelerating up along a ramp that is inclined 26.2° above the horizontal. the propulsion force pushing the motorcycle up the ramp is 3106 n, and air resistance produces a force of 286 n that opposes the motion. find the magnitude of the motorcycle's acceleration.

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

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

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
