•• I P A white-crowned sparrow flying horizontally with a speed of 1.80 m/s folds its wings and begins to drop in free fall. How far does the sparrow fall after traveling a horizontal distance of 0.500 m? If the sparrow’s initial speed is increased, does the distance of fall increase, decrease, or stay the same? Graph and solve .
• An astronaut on the planet Zircon tosses a rock horizontally witha speed of 6.95 m>s. The rock falls through a vertical distance of1.40 m and lands a horizontal distance of 8.75 m from the astronaut. What is the acceleration due to gravity on Zircon?
Problem 5
You testify as an expert witness in a case involving an accident in which car A slid into the
rear of car B, which was stopped at a red light along a road headed down a hill. You determine
that the slope of the hill is 0 = 12.0°, that the cars were separated by distance d = 24.0 m
when the driver of car A put the car into a slide, and that the speed of car A at the onset of
braking was vo
18.0 . With what speed did car A hit car B if the coefficient of kinetic
friction was 0.60?
