Answer:
1.927 m/s^2
Explanation:
period = 2 pi sqrt ( l/g)
3.2 = 2 pi sqrt (.5/g) =1.927 m/s^2
In this scenario, only conservative force is acting on the ice-cream hence energy is conserved.
Now, you know that ice-cream was held at a height of 1.75 m from ground. Taking ground( h= 0 meters) as reference,
Total energy of ice-cream before it fell = Total energy after it reached the ground.
Once ice-cream falls, all its GPE is converted into kinetic energy. Kinetic energy will be maximum just before it hits the ground. And since ice-cream is inelastic substance, it will come to at rest. That is, its GPE will be zero on the ground
Im pretty sure the answer is c; velocity is usually measure by a vector :)
Answer:B
Explanation:
Because chemical energy fuels your body with energy so without it u wont have enough energy to move.
