A toy train moves 40m in 20s at the constant velocity. What is the toy’s velocity? *
1 point

2 m/s

Explanation:

Velocity is a vector quantity that is given by:

where

d is the displacement of the object (a vector indicating its change in position)

t is the time elapsed

Note that since velocity is a vector, it has both a magnitude and a direction (the same as the displacement).

For the toy train in this problem, we have:

d = 40 m (displacement)

t = 20 s (time elapsed)

So, its velocity is:

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
