Is the positive of the answer which is your irregular speed
Answer:
30m/ s
Explanation:
this is an example of a projectile, where the path traced by the ball will be a downward parabola.
one must know that the <em>vertical velocity of an object having projectile motion is zero at the top of its trajectory</em> and that the <em>horizontal velocity remains constant throughout</em>.
this means, at the top of the trajectory the <u>ball's overall speed will be equal to its horizontal velocity</u>.
and horizontal velocity is given 30 m/s
hence, overall speed of the ball = 30m/ s
Is it just me or can anyone else not see a graph? (Because I can’t)
Answer:
A
Explanation:
In section A, she is moving in constant speed because there's a flat line which indicates speed remained same as time passed. In section c, there's a flat line but look at y axis for this one, it is 0 which means there's no speed during this part. B and D have varying speeds as there is a change in y axis variables as time passes.
