Answer:
Unbalanced forces
Explanation:
Unbalanced forces acting on an object can change the object's speed, causing it to speed up or slow down.
From the diagram The value of cos C × sin A = 
<h3>Determine the numerical value of cos C × sin A</h3>
First step : determine the values of cos C and sin A
cos C = adjacent / hypotenuse
= a / b
= 
= √3/2
sin A = sin 60⁰
= √3/2
Therefore the numerical value of cos C * sin A =
In conclusion From the diagram The value of cos C × sin A =

The three main ideas related to Newton’s Second Law are as follows :
1.Acceleration is the result of
unbalanced forces.
2.A larger force makes a
proportionally larger acceleration.
3.Acceleration is inversely
proportional to mass.

-- When the man at the North end throws the ball, the canoe
accelerates to the North.
-- While the ball is in flight, traveling south by the length of the
canoe, the canoe moves northward at a constant speed.
-- If the man at the south end misses the ball and fails to catch it,
then the canoe continues moving south at a constant speed, even
after the ball has passed him.
-- If the man at the south end successfully catches the ball, then the
canoe accelerates south at that moment, and comes to rest in the water.
