A car goes from 80 kn/h to 20 km/h in 0.5 h. What is the acceleration in km/h^2? *
jekas [21]

Answer:

<h2>In physics, acceleration is defined as the rate of change of the velocity of an object with respect to time. That is A = VF - VI /T; </h2><h2></h2><h2>Where A =  Acceleration </h2><h2>VF = Final velocity = 20 km </h2><h2>VI = Initial velocity = 80 km </h2><h2>T= Time = 0.5 hr </h2><h2>A = (20 - 80)/ 0.5 = - 60/.5  </h2><h2>A = - 120 Km/ hr^2 </h2><h2></h2><h2>Therefore, the acceleration of the car is -120 km/hr^2. </h2><h2> Because the value is negative, the appropriate name that describe it is deceleration.</h2><h2>I Hope this helps</h2>

Answer:

Well that depends on the force that is being applied onto the table and how much is being forced back

Explanation:

When learning about net force there should be some numbers with a N next to them showing you the direction of the newtons. In order to solve this problem and figure out the net force you have to subtract the newtons ( larger number first no negative newtons) then the largest newton after the subtraction the direction is the same direction as the biggest number

Example: 20N⬆️

30N⬇️

Subtract 30-20=10N⬇️
