To measure the gravity on a new planet, scientist constructed a tower and timed how long an object took to hit the surface of the planet after being dropped. If the tower was 50 meters high and the object took 4 seconds to fall, what is the acceleration due to gravity of the planet?​

Answers

Answer 1

Answer:

d = 0.294 m

1)  g = k*d/m

To find k:  k = 4π²*m/T²

T = 16.3/11 = 1.4818 sec

So

k = 4.495 N/m

Using (1),

g = 4.495*0.294/0.25 = 5.286 m/s²

Friction converts Kinetic energy to what type of energy?​

Answers

Answer: Friction between the two surfaces converts kinetic energy into thermal energy.

Explanation: Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
