Tired of being chased by a jaguar, you set a trap. Hoping to drop it on the jaguar, you try to push a 44.0 kg stone boulder off of the edge of a cliff that slopes down at an angle of 15.0°. Being weak with

hunger, the best you can do is push the boulder with a force of 222 N. The coefficient of kinetic friction

between the boulder and the ground is is 0.700. (Ignore static friction.)

What is the acceleration of the boulder while you push it down the incline?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
