So from here we can say that we adopt the positive direction choice which we can use in this textbook.
00:15
So from here we can say that the equation t from here is equal to dall of x divided by the v of x.
00:23
That is equal to 22 meter divided by the 25 multiplied by the cost of 40 degree.
00:30
So, simplifying this term, we get the value of t, that is equal to 1 .15 second.
00:36
Now, we know that the vertical distance, that is stile of i is equals to v0, sine of theta, not, multiply by the t minus 1 divided by 2 of gt raised to the power 2.
00:47
So, plugging into the value, that is 25, multiply by the sign of 40 degree, multiply by the 1 .15, minus 1 divided by 2, multiply by the 9 .8, by a 1 .5 raise to the power 2...
