3. 2 meters per second 4. i think object 7. i’ll try to figure it out 8. .77 9. 25km 10. 10m each second
Answer:
here is the answer its a picture
Explanation:
Velocity 0.86m/s
0.13J
Explanation:
Given parameters:
Mass = 0.343kg
distance = 5m
time taken = 5.8s
Unknown:
Velocity of mass = ?
Kinetic energy = ?
Solution:
Velocity is the rate of change of displacement with time. It is a vector quantity that shows magnitude and direction.
Mathematically;
Velocity =
Velocity =
= 0.86m/s
Kinetic energy is the energy due to the motion of a body. It is expressed mathematically as:
Kinetic energy = ![\frac{1}{2} m v^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%20m%20v%5E%7B2%7D)
m is the mass
v is the velocity
Kinetic energy =
= 0.13J
