A child in a car tosses a ball upward so that after release it requires 1/2 second to rise and fall back into the child's hand at the same height from which it was released. The car is traveling at a constant speed of 10 meters / second in the horizontal direction.
Between release and catch, how far did the ball travel in the horizontal direction?
5meters
As observed by a passenger in the car, what was the path of the ball from its release until the instant it was caught?
Constant then up and down with the moving car
Sketch the path of the ball as observed by a line of people standing along the side of the road. Describe your sketch. What was shape of the path of the ball?
An increasing line till it starts to decline _____-----____
Is the path curved? If so can you describe the nature of the curve.
How fast was the ball moving in the vertical direction at the instant of release? At that instant, what is its velocity as observed by a line of people standing along the side of the road?
2.45m/s 14.9m/s
Neither of these answers is correct, and it's not clear how you got either of the answers.
