What is the acceleration of a boy on a skateboard if the net force on the boy is 15 N? The total mass of the boy and the skatebo ard is 58 kg.
2 answers:
Force = (mass) x (acceleration) If the full 15N is pointing parallel to the ground, then 15 N = (58 kg) x (acceleration). Divide each side by 58 kg: Acceleration = 15 N / 58 kg = (15 kg-m/s²) / (58 kg) = (15/58) (kg-m/kg-s²) = 0.26 m/s² .
Force = mass*acceleration 15 = 58 * x x = 15 / 58 x = 0.26m/s²

Answer:
The biggest factor affecting coastal erosion is the strength of the waves breaking along the coastline. A wave's strength is controlled by its fetch and the wind speed. Longer fetches & stronger winds create bigger, more powerful waves that have more erosive power.

inverted, real, behind the lens is the answer
Well let’s put it this way. To find the neutrons you subtract the atomic atomic Nuremberg from the atomic mass. So
Mass=81-Number=28
81-28=53
Final answer is 53.
Velocity increases with speed
