Explanation:
From the exercise we have <em><u>initial height and final X position</u></em>
a) From the concept of <u>free falling objects</u> we have that
Since the car runs off the edge of the table, that means the car is moving in x direction with and at the end of the motion
<em><u>Solving for t </u></em>
t=± 0.6072 s
Since the time can not be negative, the answer is t=0.6072 s
b) To find the <u>horizontal velocity</u> of the car, we need to use the time that we just calculate
First calculate the <em>percentage of one hr</em> it takes. You can do this by dividing the distance by the velocity. The general formula for this is:
always remember to make sure your units are the same.
so that's 1km by the 950km/h velocity.
1/950 = 0.0010526 hrs
Then multiply that answer by 3600 (<em>the number of seconds in 1 hr</em>) to find how many seconds this is.
0.0010526 * 3600 = 3.789 seconds
