Distance traveled by car =14m
Total time taken =2sec
Speed =distance / time
=14m/2sec
speed=7 m/sec
Answer:
Answer is (C)
Explanation:
<u>For</u><u> </u><u>acceleration</u>
• If the motion is vertically, then acceleration is 9.8 m/s²
» Upward motion, acceleration is negative (-9.8)
» Downward motion, acceleration is positive (+9.8)
<u>For</u><u> </u><u>velocity</u>
The chemical symbol always begins with a capital letter.

Answer:
C - wasted output energy = useful output energy
Explanation:
Useful output + wasted output ALWAYS equals input energy. If the device is 50% efficient, that means that 50% of the input energy is converted into useful output energy, and 50% is converted to wasted output energy. The wasted output energy is equal to the useful output energy.
Answer:
diretion and speed will change
Explanation:
Take for example you take a sh*t off a roof and it is fired at 30 degrees it will be pulled to 0 degrees and it will and decrease in speed because of air there will be drag but it will surely land on some one.
(DON'T TAKE ANY OF THIS SERIOUSLY)
