Step-by-step explanation:
This should give you an idea the acceleration here is 9.81 because gravity and the equation is a kinematic equation
Answer:
See solution below
Step-by-step explanation:
Given the expression

Recall that
cos x = sin(90-x)
cos(x+30 ) = sin (90-(x+30)
= sin(90-x-30)
= sin(60-x)
Substitute
