Answer:

Linda started moving out and then stopped moving after 6 seconds

Explanation:

On the axes of the graph, one can see that the lower axis is labeled (time). Time can only move forward, thus the graph will forever continue leftwards.

The verticle axis is labeled (Position in (m)), this changes relative to the motion that Linda takes. As one can see, from (0) to (6) seconds Linda was moving forward, as her position in meters was increasing. however, at 6 seconds she stopped moving, thus the graph remained a horizontal line. Therefore, the answer is the following:

Linda started moving out and then stopped moving after 6 seconds.

How do veins control the flow of blood
Alik [6]
Answer: Blood primarily moves in the veins by the rhythmic movement of smooth muscle in the vessel wall and by the action of the skeletal muscle as the body moves. Because most veins must move blood against the pull of gravity, blood is prevented from flowing backward in the veins by one-way valves.

Good luck !

A 54 kg man holding a 0.65 kg ball stands on a frozen pond next to a wall. He throws the ball at the wall with a speed of 12.1 m
Inessa [10]

Answer:

The velocity of the man is 0.144 m/s

Explanation:

This is a case of conservation of momentum.

The momentum of the moving ball before it was caught must equal the momentum of the man and the ball after he catches the ball.

Mass of ball = 0.65 kg

Mass of the man = 54 kg

Velocity of the ball = 12.1 m/s

Before collision, momentum of the ball = mass x velocity

= 0.65 x 12.1 = 7.865 kg-m/s

After collision the momentum of the man and ball system is

(0.65 + 54)Vf = 54.65Vf

Where Vf is their final common velocity.

Equating the initial and final momentum,

7.865 = 54.65Vf

Vf = 7.865/54.65 = 0.144 m/s

A basketball player passes a ball to a teammate at a velocity of 6 m/s. The ball has a mass of 0.51 kg. If the original player h
Vilka [71]

We can solve the problem by using conservation of momentum.

The player + ball system is an isolated system (there is no net force on it), therefore the total momentum must be conserved. Assuming the player is initially at rest with the ball, the total initial momentum is zero:

p_i = 0

The total final momentum is:

p_f = p_p + p_b

where p_p is the momentum of the player and p_b is the momentum of the ball.

The momentum of the ball is: p_b = mv=(0.51 kg)(6 m/s)=3.06 kg m/s

While the momentum of the player is: p_p = Mv_p, where M=59 kg is the player's mass and vp is his velocity. Since momentum must be conserved,

p_f = p_i = 0

so we can write

p_f = Mv_p + p_b =0

and we find

v_p = -\frac{p_b}{M}=-\frac{3.06 kg m/s}{59 kg}=-0.052 m/s

and the negative sign means that it is in the opposite direction of the ball.
