A ball rolls off the edge of a balcony at 10 m/s. What is its speed after 1 s in the air

V = 19.8 m/s

Explanation:

Given the following data:

Initial velocity = 10m/s

Time, t = 1 secs

We know that acceleration due to gravity is equal to 9.8m/s

To find the final velocity, we would use the first equation of motion;

Where;

V is the final velocity.

U is the initial velocity.

a is the acceleration.

t is the time measured in seconds.

Substituting into the formula, we have;

V = 10 + 9.8*1

V = 10 + 9.8

V = 19.8 m/s

vapour or gas assuming atmospheriv pressure

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
