Because the more advances made in the world means the more we can learn on how things work and how we can better the lives of humans and other species. If we didn't have scientific advancements we wouldn't have cell phones, electric, tv, car, computers, ect. We would still be living in Cave man era with clubs and horrible language skills.

A bird flies at a speed of 2.3 m/s if it has 14 j of kinetic energy what is the mass
Sidana [21]
Kinetic Energy =  1/2 * mv²

Kinetic Energy = 14 J,  v = 2.3 m/s ,  m = ?

14  =      1/2 * m* 2.3²

14 = 0.5*m*2.3*2.3

m =  14 / (0.5*2.3*2.3)

m = 5.29 kg.

Mass = 5.29 kg.

Una pelota recorre 20 m hacia la derecha y luego 10 m hacia la izquierda, todo en un lapso de tiempo de 10 s , cual es si veloci
zvonat [6]

Answer:

v = 1  i ^ m / s,   v = 1 m / s

Explanation:

In this problem we show the difference between vectors and scalars.

The average speed is

          v = Δx / Δt

The bold are vectors            

          Δx = 20-10 = 10 i^  m

           v = 10/10

           v = 1  i ^ m / s

the unit vector indicates that the velocity is on the x-axis

The average speed is

           v =Δx / Δt

           v = 10/10

           v = 1 m / s

in this case we have a scalar
