Thinking about an analogue clock, calculate the angular displacement in revolutions, radians and degrees for the following: • A second hand after three minutes An hour hand after 20 minutes The minute hand as it moves from 9.15 to 12.45.

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four

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?
