Answer:

150.5 m

Explanation:

The motion of the car is a uniformly accelerated motion, so we can use the following suvat equation to find the displacement:

s=ut+\frac{1}{2}at^2

where

s is the displacement

u is the initial velocity

t is the time

a is the acceleration

For the car in this problem,

u = 0

a=3.8 m/s^2

Substituting t = 8.9 s, we find the displacement of the car at that time:

s=0+\frac{1}{2}(3.8)(8.9)^2=150.5 m

A railroad car containing an angry bull is standing onthe
nata0808 [166]

Answer:

v_{f} = - M / m v

Explanation:

We must define a system formed by the wagon and the torro, in this case the forces of the movement are internal, so the moment is preserved, write the moment in two moments

Initial. Before the bull's movement, in this case the two are still

             p₀ = 0

Final. The bull is moving

            p_{f}= M v + m v_{f}

             p₀ = p_{f}

              0 = M v + mv_{f}

We cleared the train speed

            v_{f} = - M / m v

The negative sign indicates that the train moves in the opposite direction of the bull
