To solve this problem we will apply the linear motion kinematic equations. From the definition of the final velocity, as the sum between the initial velocity and the product between the acceleration (gravity) by time, we will find the final velocity. From the second law of kinematics, we will find the vertical position traveled.
Here,
v = Final velocity
= Initial velocity
g = Acceleration due to gravity
t = Time
At t = 4s, v = -30m/s (Downward)
Therefore the initial velocity will be
Now the position can be calculated as,
When it has the ground, y=0 and the time is t=4s,
Therefore the cliff was initially to 41.6m from the ground
It's 120N downwards. net force is adding or subtracting the x and y values
Answer:
- gravitational 2.force of gravity
Explanation:
1.it ocours when an object is thrown into the sky. 2.iy ocurs when an object is falling or being pulled from the sky
The ears are superior and posterior to the shoulders and lateral to the nose.
Answer:
The circulatory system breaks down food and gets / absorbs nutrients. The muscular system works to get nutrients to the rest of the body. The nervous system basically controls the digestive system and sends information to the brain.
I'm pretty sure I'm right, but please correct me if I'm wrong! :)
