The initial velocity of a car moving along a straight path was 0 meters/second. after 10 seconds it reached a velocity of 25 meters/seconds. calculate the cars average acceleration during this time period.

given that

initial velocity of car = 0 m/s

after t = 10 s

final velocity of the car = 25 m/s

now for average acceleration we can use

so here the acceleration will be 2.5 m/s^2

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

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.
