How long would it take a car traveling from 0 mph to 203 mph top speed to go 12.42 miles?

0.12h (approx.)

Explanation:

(Note: If the mph stands for miles per hour)

Given that: Initial Velocity (u) = 0mph

Final Velocity (v) = 203mph

Distance (s) = 12.42miles

Time (t) = ?

Using the first equation of motion:

S={(v+u)÷2}×t

12.42={(203+0)÷2}×t

12.42={203÷2}×t

12.42={101.5}×t

12.42={101.5}t

t=12.42÷101.5

t=0.122364532h

t=0.12h (approximately)

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.
