As a train accelerates away from a station, it reaches a speed of 4.7 m/s in 5 s. if the train’s acceleration remains constant, what is its speed after an addition 6 s has elapsed

5.64

Explanation:

if in 5 s it reached 4.7 m/s then in 1 s it would reach .94 m/s. and .94 mps every second for 6 seconds adds up to 5.64 m/s

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.
