The relevant equation to use here is:

y = v0 t + 0.5 g t^2

where y is the vertical distance, v0 is initial velocity = 0, t is time, g = 9.8 m/s^2

y = 0 + 0.5 * 9.8 * 3^2

<span>y = 44.1 meters</span>

two cars are travelling side by side down a straight road in opposite directions. both cars are travelling at a speed of 22 m/s.

Nimfa-mama [501]

Answer: 44m/s

Explanation:

Speed of Car A travelling left = 22m/s

Speed of Car B travelling right = 22m/s

Now recall that relative speed of objects moving in opposite directions is equal to the sum of each speed

Hence, Relative speed = (Speed of Car A + Speed of Car B)

= (22m/s + 22m/s)

= 44m/s

Beth moves a 15 N book 20 meters in 10 seconds. How much power was produced?

Mice21 [21]

Answer:

30 Watts

Explanation:

Power = Work/Time

Work = Force*Distance

Power = Force * Distance / Time

Power = 15 N * 20 meters / 10 sec

Power = 30 Watts

An object travels a given distance at a speed of 5 m/s. If the object travels the same distance at a higher speed, how will the

makkiz [27]

You’re traveling be same distance, but since it’s at a higher speed, you’re going faster than you were before. This meaning that it will take less time.
