A tennis ball receives a top spin when struck by a racket and describes a curved trajectory. The top spin implies that the rotatory motion of the top surface of the ball is in the direction of the translatory motion of the ball. Which one of the following statements is the best description of the trajectory ?

Engineering

Physics

Circular Motion in Vertical Plane

Motion of Charged Particle in Uniform Magnetic Field

BernoulIis Equation and Equation of Continuity

Question

A tennis ball receives a top spin when struck by a racket and describes a curved trajectory. The top spin implies that the rotatory motion of the top surface of the ball is in the direction of the translatory motion of the ball. Which one of the following statements is the best description of the trajectory ?

Pressure on the top surface is higher; trajectory rises

Pressure on the top surface is lower; trajectory rises

Pressure on the top surface is lower; trajectory dips

Pressure on the top surface is higher; trajectory dips
