The following force diagram represents Newton’s Third Law of Motion:
Julli [10]

Answer:

<u>FALSE.</u>

Explanation:

Newton's third law states that :

  • <em>Every action has equal and opposite reaction</em>
  • <em>That is , the magnitude is the same but the directions are opposite</em>
  • <em>The action reaction forces DONOT operate on the same body.</em>

For example ,

If a block is kept on the ground , the action force is the normal force acting on it due to the ground. <em>BUT , NOTE THAT : the reaction force isn't the gravitational force on the body ! It is the normal force acting on the ground due to the block !</em>

Thus,

we conclude that action and reaction forces donot act on the same body and therefore , this case has the <u>answer : FALSE </u>

If a car travels 30 mi. north for 30 min., 60 mi. east for 1.0 hour, and 30 mi. south for 30 min., what is the average speed
Ainat [17]

Answer: 60mph

Explanation:

Given the following :

First leg travel:

Distance = 30 miles

Time of travel= 30 minutes = 0.5 hour

Second leg travel:

Distance = 60 miles

Time of travel = one hour

Average speed :

Speed = total Distance / time of travel

Total distance in miles = (30 + 60) miles = 90 miles

Total time of travel = 1 hour + 0.5 hour = 1.5 hours

Average speed = total distance traveled / total travel time

Average speed = 90 miles / 1.5 hours

Average speed = 60 miles / hour

= 60mph

If izzy mass is 0.3kg he applide 657.9n force what will be the accelration​
Sholpan [36]

Answer:

The acceleration of the body, a = 2193 m/s²

Explanation:

Given,

The mass of the body, m = 0.3 kg

The force acting on the body, F = 657.9 N

The force acting on an object is proportional to the product of mass and acceleration of the body.

                         F = m x a

Therefore, the acceleration of the body is

                           a = F / m

                              = 657.9 N / 0.3 kg

                              = 2193 m/s²

Hence, the acceleration of the body, a = 2193 m/s²
