If a car goes along a straight road heading east and speeds up from 45 ft/s to 60 ft/s in 5 s calculate the acceleration

Explanation:

It is given that initial speed of car,

Also, final speed of car,

Time taken by the car during this process,

We need to find the acceleration of car, a.

Now, by newton's equation of motion.

We know,

Putting all required values in above equation.

Therefore, the acceleration by the car during this process is

Hence, it is the required solution.

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.
