As shown in the figure below, a cow walks leftward 15\,\text m15m15, start text, m, end text to eat some flowers, then walks rightward 25\,\text m25m25, start text, m, end text to munch on some apples. The cow walks a total time of 510\,\text s510s510, start text, s, end text.

0.0196m/s

Explanation:

Since we are not ask what to calculate but we can calculate the cow's velocity.

Velocity = change in displacement/time

Change in displacement of the cow is +25-15 = 10m

Time taken = 510s

Velocity of the cow = 10/510

Velocity of the cow = 0.0196m/s

Hence the velocity of the cow is 0.0196m/s

conduction, convection, radiation

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
