Initial velocity of kangaroo in upward direction (u) = 5.77
Final velocity at the highest point of the journey (v) = 0
Let the maximum height reached be H.
Acceleration due to gravity = -9.8
Now, using the third equation of motion:
H = 1.698 m
The maximum height reached by kangaroo is 1.7 m.
Atomic bomb:
Pro: It helps keep countries at peace due to fear of destruction
Con: Very deadly and can destroy many people's lives.
Answer:
D) The ball exerts a force on the wall and the wall exerts a force back.
Explanation:
Newton's third law of motion states that:
"When an object A exerts a force on another object B, then object B exerts an equal and opposite force on object A"
In this problem, we can identify (for instance) object A with tha ball and object B with the wall. Therefore, if we apply Newton's third law, we get:
The ball (object A) exerts a force on the wall (object B), therefore the wall (object B) exerts an equal and opposite force on the ball (object A). So, option D is the correct one.
Answer:
The right answer is ball b
Explanation:
I hope it is helpful for you
because when ball b knocking bricks over than it will not able to come back
Thank you for posting your question here at brainly. Below is Yoland's study:
<span>Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m.
</span>
I think the answer is "She can use constructive interference to generate a wave with an amplitude of 1.5 m."
