a train travels 81 kilometers in 2 hours and then 88 kilometers in 2 hours what is its average speed​
Blababa [14]

Average speed = total distance / total time

= (81 + 88) / (2 + 2)

= 169/4

= 42.25 kilometers/hour

Let me know if you have any questions.

An object with the mass of 2.0 kg accelerates 2.0 m/s2 when an inknown force is applied to it what is the amount of the force
Ivahew [28]

As per Newton's II law we know that

F = ma

here F = force applied

m = mass of object = 2 kg

a = acceleration = 2 m/s^2

now as per above formula we will have

F = 2 \times 2

F = 4 N

so here applied force on the ball will be 4 N

1. A 1000 kg bag of sand has an<br> acceleration of 0.5m/s/s. What is the<br> force on the bag?
densk [106]

Answer:

We conclude that the force on the bag is 500 N.

Explanation:

Given

  • Mass m = 1000 kg
  • Acceleration a = 0.5 m/s²

To determine

Force F = ?

We know that when a force is applied to a body, it produces acceleration.

<u>Important Tip: </u>

  • We can determine the force on the bag using the formula F = ma

Using the formula

F = ma

where

  • F is the force
  • m is the mass
  • a is the acceleration

now substitute m = 1000, and a = 0.5 m/s² in the formula

F = ma

F = (1000)(0.5)

F=500 N

Therefore, we conclude that the force on the bag is 500 N.
