Explanation:

Whenever an object exerts a force on another object, the second object exerts a force o the same amount, but in the ______ direction to that of the first object. (Fill in the blank)

Answers

Answer:

Opposite

Explanation:

Newton's third law of motion states that for every action there is an equal but opposite reaction.

Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move etc,

For example, while driving down the road, a firefly strikes the windshield of a car (Action) and makes a quite obvious mess in front of the face of the driver (Reaction) i.e the firefly hit the car and the car hits the firefly.

The ultimately implies that, in every interaction, there is a pair of equal but opposite forces acting on the two interacting physical objects.

Hence, whenever any physical object exerts a force (action) on another physical object, the second physical object exerts a force (reaction) of the same amount, but acting in opposite direction to that of the first physical object.

A rookie quarter back throws a football with an initial upward velocity component of 12.0 m/s and a horizontal velocity component of 20.0 m/s. Ignore resistance. How much time is required for the football to reach the highest point of the trajectory

Answers

Answer:

t = 1.22 s

Explanation:

Given that,

The initial upward velocity component of a football = 12 m/s

The horizontal velocity component is 20 m/s

We need to find the time required for the football to reach the highest point of the trajectory. Let the time is t.

Using first equation of motion to solve it such that,

[tex]v=u+at[/tex]

u is initial velocity

v is final velocity

a = -g

so,

[tex]t=\dfrac{u}{g}\\\\t=\dfrac{12}{9.8}\\\\t=1.22\ s[/tex]

So, the required time taken by the football to reach the highest point is 1.22 seconds.

The block at Position A is released from the spring with 100 J of elastic potential energy. How
much kinetic energy does the block have at Position B? Explain how you know.

Answers

Answer:

v = 3.65 m / s

Explanation:

In this exercise we use the conservation of mechanical energy

starting point. Point A compressed spring

          Em₀ = 100 J

final point. Point B uncompressed spring

         Em_f = K = ½ m v²

energy is conserved

         Em₀ = Em₀_f

         100 = ½ m v²

         v = [tex]\sqrt{ \frac{2 \ 100 }{m} }[/tex]

         v = [tex]\sqrt {200/15}[/tex]

         

         v = 3.65 m / s

A horizontal, uniform board of weight 125 N and length 4 m is supported by vertical chains at each end. A person weighing 500 N is hanging from the board. The
tension in the right chain is 250 N.
Which of the following describes where the person is hanging?

Answers

Answer:

let Tension in the left chain is F

here, Fnet = 0

⇒F - 500N + 250 N - 125 N = 0

⇒F - 375 N = 0

⇒F = 375 N

let r from the left end of the board is the person sitting.

now torque at left end, τ = 0.

⇒375 × (0) - 500N × (r) + 250N × (4m) - 125 N × (2m) = 0

⇒0 - 500r + 1000 - 250 = 0

⇒750 = 500r

⇒r = 750/500 = 1.5 m
