Question

66 - 67. calculate the horizontal component of the balls initial velocity. show all work, including the equation and substitution with units. (2) 68 - 69. calculate the vertical component of the balls initial velocity. show all work, including the equation and substitution with units. (2) 70. on the diagram in your answer booklet, draw an arrow originating at point p that represents the direction of the balls acceleration at point p. 1

Explanation:

Step1: Identify the acceleration of the ball

The only force acting on the ball (neglecting air - resistance) is the force of gravity. According to Newton's second law \(F = ma\), and the force of gravity \(F = mg\). So the acceleration \(a=\frac{F}{m}=g\).

Step2: Determine the direction of the acceleration

The force of gravity acts downwards towards the center of the Earth. So the acceleration of the ball, which is in the direction of the net force (by Newton's second law \(F = ma\)), is vertically downwards.

Answer:

Draw an arrow originating at point \(P\) pointing vertically downwards.
