question mark

A ball is dropped from a height of 39.0 m. The wind is blowing horizontally and imparts a constant acceleration of 1.20 m/s2 to the ball. (a) Show that the path of the ball is a straight line and find the values of Rand θ in Fig. (b) How long does it take for the ball to reach the ground? (c) With what speed does the ball hit the ground?

Comparing the components two equation can be obtained

This is an equation of straight line passing through origin, which in this case is at the point from which the ball was dropped.

Therefore, the range of the ball is 4.78 m .

Therefore, the length of the hypotenuse is 39. m .

Therefore, the time of flight of ball is 2.82 s .

Therefore, the speed of the ball at the bottom is 27.8 m/s .
