Explanation :
Any object that is thrown in space that moves under the action of gravity is known as a projectile. Every object in the universe comes down due to gravitational force.
When a soccer ball is headed from the player 1 to player 2 across the soccer field, the soccer ball will act like a projectile.
In projectile motion, we can calculate certain parameters like
In apex the answer is "soccer ball"
B) increasing
C) decreasing
D) negative
The horizontal component of the velocity remains constant in a trajectory course.
Answer: A
Explanation:
The trajectory path is formed due to the gravitational pull acting on the object thrown from some point either upward or downward.
As it is known that the velocity is divided into horizontal and vertical component, the vertical component of the velocity of the object thrown will be mainly influenced by the gravitational pull as it acting in vertical direction only.
So the vertical component of the object following a trajectory path will be changing at a rate of 9.8 m/s2 which is the acceleration due to gravity.
On the other hand, the horizontal component of the velocity will remain constant in order to maintain the law of conservation of energy.
im not 100 percent sure but i think its a
Answer:
B and D
High Accuracy
Low precision
Explanation:
Its attached below!
Answer:
8 J
Explanation:
Heat = work + change in internal energy
Q = W + ΔU
15 J = 7 J + ΔU
ΔU = 8 J
