Ronnie kicks a playground ball with an initial velocity of 16 m/s at an angle of 40° relative to the ground. what is the approximate horizontal component of the initial velocity? 0.64 m/s 0.77 m/s 10.3 m/s 12.3 m/s

Respuesta :

The horizontal component of the velocity with which Ronnie kicks a playground ball is 12.3 m/s.

Horizontal component of the velocity

The horizontal component of the velocity with which Ronnie kicks a playground ball is calculated as follows;

Vx = Vcosθ

where;

  • V is the initial velocity
  • θ is the angle of projection

Vx = 16 x cos(40)

Vx = 12.3 m/s

Thus, the horizontal component of the velocity with which Ronnie kicks a playground ball is 12.3 m/s.
