Question

A player shoots a basketball as shown below. 0 Points R and Q are at the same height and S is at the top of the trajectory. All statements refer to the basketball. Coordinate system: the x-axis is horizontal and points to the right, the y-axís is vertical and points up. (Neglect air friction.) D The speed at R is... that at Q. D The acceleration at Qis.... that at R. The x-component of the velocity at S is.... that at R D The y-component of the acceleration at S is... zero. B The y-component of the velocity at R is... at Q. Submit Answer Tries 0/20

Explanation / Answer

Here ,

the speed at R is EQUAL TO that at Q

(as R and Q are at same height)

======================

the acceleration at Q is EQUAL that at R

(the acceleration is acceleration due to gravity)

=========================

the x component of the velocity at S is EQUAL that at R

(the horizontal velocity is same at all the points)

=========================

the y- component of the acceleration at S is (less than) Zero

the acceleration is downwards

=============================

the y component of velocity at R is greater than at Q

(as the y component of velocity is positive at R and negative at Q)
