Answer: x= 4.761 m/s
t=0.786 sec
Explanation: In a projectile motion (or 2D motion), the object is launched with an initial angle and an initial velocity
The components of the velocity are
<em>The magnitude, which is the speed, and the direction in which the motion is happening.</em>
Similarly the displacement has the components
The last formula is valid only if the object is launched at ground level, as our frog does.
There are two times where the value of y is zero, when t=0 (at launching time) and when it lands back from the air. We need to find that time t by making y=0
Dividing by t (assuming t different from zero)
Then we find the total flight as
Replacing this time in the formula of x
We can solve for
Knowing that x=2.20 m and °
We now compute t
Proton : 0.00000000000000000000000161726
Electron : 0.00000000000000000000000000091093
Take them away =
1.616349e−24
(that's what it gave me on the calculator when I did proton - electron)
A coil of wire with a current flowing thru it becomes a magnet
A fossil, in my opinion, is basically looking back in time when you see it. It's the bones of remains of an animal or organism that lived long ago, preserved in the ground through Earth's natural processes and dug up by paleontologists.
Hope this helped!
