An object with an initial velocity of 3.2 m/s accelerates at a rate of 1.6 m/s2 for 4 seconds. how far will it have traveled during that time?

25.6 m

Explanation:

From kinetic equation

where u is initial velocity, a is acceleration and t is time.

Substituting 3.2m/s for u, 1.6m/s2 for a and 4 s for t

Therefore, the distance is 25.6 m

we need answer choices

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.
