An object of mass 10 kg is released at point a, slides to the bottom of the 30º incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.75 m. (see below.) the spring constant is 500 n/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless. what is the speed of the object at the bottom of the incline?

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
