Answer:
<h2>
3.94 kg</h2>
Explanation:
Given,
Force ( f ) = 30 N
Acceleration(a) = 7.6 m/s
Now, Let's find the mass of the ball
Using the Newton's second law of motion:
We get:
plug the value
Use the commutative property to reorder the terms
Swap the sides of the equation
Divide both sides of the equation by 7.6
Calculate
Hope this helps..
Best regards!!
Machines makes work easier by increasing the amount of force that is applied, and changing the direction in which the force is applied !! Hope it helped (p.s. I had this same question)
Because polymers are covalently bonded material, and metals are metalicly bonded material.
Covalent bonds do not let atoms exchange electrons like metalic bonds do.
