Welcome to this lesson.
00:03
In this lesson we have a panther that jumps to a height of 2 .55m while living on the ground at an angle of 42 degrees.
00:12
So we are looking at the initial speed in meters per second.
00:17
So here we have the height which is equals to v times sine 2 theta on 2 times v where v is the initial velocity.
00:42
So the initial velocity was given, was actually not given, that's what we are looking for.
00:49
And we have the theta, that is the angle.
00:54
So the angle formed with the horizontal side which was given as 42 .0 degrees.
01:03
And we have, which is the acceleration due to gravity which we will have as 9 .81 meters per second squared.
01:24
So here we have the h which was 2 .55 and that is equals to the v squared times sine 42 times 2 all divided by 2 times 9 .81.
01:45
So here we have 2 .55 which is equals to v squared times sine 42 times 2 which is 84 degrees.
01:59
So this will be 19 .62...
