A i think because it’s talking about covering ground, a faster car would cover more ground.
Guessing you want the average speed. We can multiple each speed by the time we spent going that speed, and them all together and then divide by the total time we spent in traffic to get the average speed. We spent a total of 7.5 minutes in traffic, so average speed = (12*1.5+0*3.5+15*2.5)/7.5 = 7.4 m/s
A :-) 1.) 3rd law of motion.
2.) 2nd law of motion ( law of inertia ).
- 2nd law states that if an object has more mass then it has more inertia ( mass = inertia ).
So , here the empty shopping cart is easier to push compared to loaded one.
3.) 1st law of motion.
- 1st law states that a object in rest will stay at rest , if a object is in motion it will stay at motion until a unbalanced force is applied on it.
So , here the baseball was in motion then , an unbalanced force ( bat ) was applied on it , so the was thrown up into the air.
4.) 3rd law of motion.
- 3rd law states that every action force has an equal and opposite reaction force.
So , here when your walking , your foot pushes the ground backwards ( action force ) , and the ground pushes your foot forward ( reaction force ).
5.) 1st law of motion.
