Question

A ball is dropped from top of a tower in a high speed wind .The wind exerts steady force on the ball.The path followed by the ball is? (a)parabola (b)circular arc (c) elliptical arc (d) straight line

Answer 1

A ball is dropped from the top of a tower in the high-speed wind. The wind exerts a steady force on the ball. The path followed by the ball is (d) straight line

• we know that x = ut+1/2* a$t^{2}$
• Here initial velocity u = 0
• therefore the equation becomes 1/2* a$t^{2}$
• as the ball dropped from the tower here a is equal to the g the gravitational constant
• after dividing both the equation 1/2* a$t^{2}$ and  1/2* g$t^{2}$
• we will get y= n*x where n = constant
• and it is an equation of straight line hence, the answer will be a straight line.
