A golfer drives her golf ball from the tee down the fairway in a high arcing shot. When the ball is at the highest point of its flight

a) the velocity and acceleration are both zero
b), The x-velocity is zero and thе y-velocity is zero
c) the x-velocity is non-zero, but the y-velocity is zero
d) thе velocity iѕ non- zero, but the acceleration is zero​

Respuesta :

Answer:

Correct Choice: c)

Explanation:

When an object is launched with an angle with respect to the horizontal, it describes a curved path exclusively under the action of gravity.

The velocity at any point of the path has two components:

The horizontal component has a constant value because no acceleration acts in that direction.

The vertical component has a variable value that depends on the acceleration of gravity and the time.

When the golfer drives the golf ball in a high arcing shot it reaches a maximum height and then returns to the ground.

a) The velocity is never zero until the ball hits the ground. The acceleration is never zero. False

b) The x-velocity is constant and equal to the horizontal component of the initial velocity. The y-velocity is zero at the highest point. Only one condition is true, thus the whole statement is False.

c) The x-velocity is never zero, and the y-velocity is zero as explained above. True

d) The velocity is non-zero, and the acceleration is not zero. False

Its velocity as well as acceleration are both non-zero.

  • This seems to be attributable to the reality that towards the maximum height, just the vertical dimension of that though velocity approaches zero. These same horizontal parts are already in play. As a result, the velocity would be non-zero.
  • Gravity's acceleration would operate upon that ball, hence the acceleration will then be non-zero.

As a result, the aforementioned response is correct.
