Two astronauts on opposite ends of a spaceship are comparing lunches. One has an apple, the other has an orange. They decide to

trade. Astronaut 1 tosses the 0.110 kg apple toward astronaut 2 with a speed of vi,1 = 1.13 m/s . The 0.150 kg orange is tossed from astronaut 2 to astronaut 1 with a speed of 1.25 m/s . Unfortunately, the fruits collide, sending the orange off with a speed of 0.977 m/s in the negative y direction.

Answer:

The speed and direction of the apple is 1.448 m/s and 66.65°.

Explanation:

Given that,

Mass of apple = 0.110 kg

Speed = 1.13 m/s

Mass of orange = 0.150 kg

Speed = 1.25 m/s

Suppose we find the final speed and direction of the apple in this case

Using conservation of momentum:

Before:

In x direction,

P_{b}=m_{p}v_{p}-m_{o}v_{o}

P_{b}=0.110\times1.13-0.150\times1.25

P_{b}=−0.0632\ kg-m/s

In y direction = 0

After:

v_{ay} is velocity of the apple in the y direction

v_{ax} is the velocity of the apple in the x direction

Momentum again:

In x direction,

0.110\times v_{ax}+0=−0.0632

v_{x}=\dfrac{−0.0632}{0.110}

v_{x}=−0.574\ m/s

In y-direction,

0.110\times v_{ay}-0.150\times0.977=0

v_{ay}=\dfrac{0.150\times0.977}{0.110}

v_{ay}=1.33\ m/s

We need to calculate the speed of apple

v_{a}=\sqrt{(v_{x})^2+(v_{y})^2}

Put the value into the formula

v_{a}=\sqrt{(−0.574)^2+(1.33)^2}

v_{a}=1.448\ m/s

We need to calculate the direction of the apple

Using formula of angle

\tan\theta=\dfrac{v_{ay}}{v_{ax}}

Put the value into the formula

\theta=\tan^{-1}(\dfrac{1.33}{0.574})

\theta=66.65^{\circ}

Hence, The speed and direction of the apple is 1.448 m/s and 66.65°.

A force of 350N is applied to a body. If the work done is 40kJ, what is the distance through which the body moved?
Studentka2010 [4]

The distance covered by the body is 114.3 m

Explanation:

The work done by a force exerted on an object is given by

W=Fd cos \theta

where

F is the magnitude of the force

d is the displacement of the object

\theta is the angle between the direction of the force and of the displacement

For the object in this problem, we have

F = 350 N is the force applied

W=40 kJ = 40,000 J is the work done

\theta=0^{\circ} if we assume that the force is applied parallel to the motion of the object

Solving for d, we find the distance covered by the object:

d=\frac{W}{F cos \theta}=\frac{40,000}{(350)(cos 0)}=114.3 m

Which set of shapes contains members that are always similar to one another?
Colt1911 [192]
<span>The correct answer is option C. i.e.Equilateral triangles. All equilateral triangle have equal sides. Due to this these set of shapes will always be similar. Similarity in the sense that only the size of the triangles can change to large or smaller but the shape will be be similar always.</span>

Please help with these physics problems 1. A soccer ball is dropped from the top of a building. It takes 5.8 seconds to fall to
Tatiana [17]

Answer:

1.) h = 164.8 m

2.) U = 49.1 m/s

3.) t = 1.43 seconds

Explanation:

1.) A soccer ball is dropped from the top of a building. It takes 5.8 seconds to fall to the ground. The height of the building is...? 

Since the soccer ball is dropped from the building, the initial velocity U will be equal to zero

Using second equation of motion

h = Ut + 1/2gt^2

Substitutes the time into the formula

h = 1/2 × 9.8 × 5.8^2

h = 164.8 m

2. The Falcon 9 launches to a height of 123 meters. What is its vertical initial velocity?

At maximum height final velocity = 0

Using the third law of motion

V^2 = U^2 - 2gH

0 = U^2 - 2 × 9.8 × 123

U^2 = 2410.8

U = 49.1 m/s

3. An apple falls from rest off a 10.m m tree. How long will it take before it hits the ground?

Since the apple fall from rest, the initial velocity U will be equal to zero

Using the second equation of motion,

h = Ut + 1/2gt^2

substitute all the parameters into the formula

10 = 1/2 × 9.8 × t^2

10 = 4.9t^2

t^2 = 10/4.9

t^2 = 2.04

t = 1.43 seconds
