Answer:
h = 181.73 m
Explanation:
given,
distance between the neighbors = 42 m
speed of the rock rolling = 6.9 m/s
vertical velocity of ball = 0 m/s
height of the cliff = ?
time taken by the ball to travel 42 m
d = s x t
s is the horizontal speed of the ball equal to 6.9 m/s
t = 6.09 s
same time will be taken by the ball to travel vertical distance
Using equation of motion
h = 181.73 m
Answer:
Explanation:
the force that you applied caused the notebook to move.
the force applied on the notebook by the table causes it to stop moving.
this is because after sometime the book uses up the force and later the force you applied is less than that of the force by the table.
Answer:
Depends.
Explanation:
Whether the object is going left or right, the speed will stay the same until friction eventually stops it. <em>However, </em>if, for example, we're talking about an object going straight before veering right, then yes, speed <em>does</em> matter. An object will normally have to speed up or slow down momentarily when changing direction to keep itself sustained on the ground.
So, honestly? It really depends on what we're talking about!
Hope this helped!
