“Suppose you begin sliding down a 15 degree ski slope. Ignoring friction and air resistance, how fast will you be moving after 10 seconds?”
acceleration a = g sin Θ = 9.8 sin15 = 2.5 m/s²
a = (vf – vi)/t or
vf = vi + at
= 0 + 2.5(10)
= 25 m/s
The penny’s speed relies upon on how lots mass the international has “gravity”… Now as quickly as the penny is dropped that is going to start to fall with a persevering with acceleration relative to the mass the international the penny is falling to, has. speed = (acceleration) * 369…. or something like that. i’m to lazy to come across the actual “gravitational” pull of earth.
