If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 5 m/s2 for 3 seconds, what will its final velocity be?

25 m/s

Explanation:

Formula of acceleration is:

where,

v is the final velocity

u is the initial velocity

a is the acceleration and

t is the time

so plugging in the values we get,

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.
