Since this is a horizontal throw, so v0 x is 42 meter per second, and v0y is going to be 0, and acceleration is acceleration due to gravity, which is downwards, so we have a negative sign here.
00:16
And we are given x minus x not to be 60 .5 feet.
00:21
Note that one fate is equal to 0 .3048 meter.
00:32
And just to reach this one.
00:37
We can use the equations for the projectile motion using these variables.
00:44
Next for the vertical displacement, h, which we need to find, we will first start with finding the time taken by the particle to travel from this point to here.
01:01
Basically the time taken by the particle to hit the ground.
01:06
So we will use x minus x0 to be v0x t plus half a xt square.
01:14
But you can see here a x is zero because there is no acceleration in the x direction.
01:21
So this is basically zero and this gives x minus x not to be equal to v0x.
01:30
And using this equation we can solve the we can solve for time of travel this is equal to 60 .5 feet we need to convert this feet into meters just to be consistent with the units because our velocity is given in meter per second meter per feet over velocity which is 42 meter per second and we find this time to be 0 .4391 second...
