That's the cool thing about free fall. The amount of time it takes to fall remains the same.
In this case, a ball that is simply dropped from rest will fall at the same rate as a ball that had some umph in the horizontal direction.
Answer:
non-accelerated movement
velocity versus time a horizontal straight line.
distance versus time gives a horizontal straight line.
accelerated motion
graph of velocity versus time s an inclined line and the slope
graph of distance versus time is a parabola of the form
Explanation:
In kinematics there are two types of steely and non-accelerated movements
In a the velocity of the body is constant therefore a speed hook against time gives a horizontal straight line.
A graph of distance versus time is a straight line whose slope is the velocity of the body
x = v t
In an accelerated motion the velocity changes linearly with time, so a graph of velocity versus time is an inclined line and the slope is the value of the acceleration of the body
v = v₀ + a t
A graph of distance versus time is a parabola of the form
x =v₀ t + ½ a t²
Answer:
increase speed, decrease speed, and change direction
Explanation:
Answer:
Explanation:
Total tension must support the weight of the child and provide the necessary centripetal force.
2T = m(g + v²/R)
2(414) = 35.0(9.81 + v²/3.02)
828 = 35.0(9.81 + v²/3.02)
23.65 = 9.81 + v²/3.02
13.847 = v²/3.02
41.81 = v²
v = 6.47 m/s
F = 2(414) = 828 N (ignoring the weight of the chains and seat)
