A car goes at a speed of 100 k / h. Suddenly, at a distance of 50 m, the driver notices an obstacle. Is it possible to avoid collision if you decelerate at 4.9m/s^2?

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

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.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
