Hello, here we have to solve the following problem.
00:02
Soccer bow is kicked with an initial velocity of 25 meters per second at an angle of 45 degree below the horizontal.
00:11
First, in question a, we have to find the vertical component of acceleration as it travels along its trajectory.
00:22
So here we have to find a vertical.
00:26
So let's make a quick sketch.
00:33
This motion occurs under the gravity only.
00:36
That's why this vertical comes.
00:37
Component is negative j which is negative 9 .8 meters per square second.
00:43
In question b we have to determine horizontal component of the initial velocity.
00:50
That is b0 cosine alpha.
00:56
Let's calculate it...
