Answer:
Part a)
Velocity = 6.9 m/s
Part b)
Position = (3.6 m, 5.175 m)
Explanation:
Initial position of the particle is ORIGIN
also it initial speed is along +X direction given as
now the acceleration is given as
when particle reaches to its maximum x coordinate then its velocity in x direction will become zero
so we will have
Part a)
the velocity of the particle at this moment in Y direction is given as
Part b)
X coordinate of the particle at this time
Y coordinate of the particle at this time
so position is given as (3.6 m, 5.175 m)
The acceleration of an object in free fall is
Explanation:
We can solve the problem by using Newton's second law of motion, which states that:
where
F is the net force on an object
m is the mass of the object
a is its acceleration
For the object in this problem, we have:
m = 9.9 kg is its mass
F = 97.02 N is the net force on the object
So, we can rearrange the equation to find its acceleration:
This value is actually known as acceleration of gravity (g), and it is the acceleration that any object in free fall has near the Earth's surface, regardless of its mass.
