A car travels 35 km west and 90 km north in two hours what is its average velocity?

blagie [28]

Average velocity = Total Displacement / Total time taken

Total displacement is the distance from starting to end point.

35km west then 90km north. When you will draw this and connect starting to end point. You will get a right angled triangle.

So displacement = $\sqrt{35^2+90^2}$

= 96.56 km

So, Total displacement = 96.56 km

So, Average Velocity = 96.56 / 2 = 48.28 km/hr

As you are cycling to the Q center one spring day, you pass the construction site at Gant and stop to watch a few minutes. A cra

Rama09 [41]

Answer:

30.63 m

Explanation:

Using y = ut + 1/2gt² where u = initial speed of block = 0 m/s, g = acceleration due to gravity = 9.8 m/s² and t = time of fall = 2.5 s and y = height of fall.

So, substituting the values of the variables into the equation, we have

y = ut + 1/2gt²

y = 0 m/s × 2.5 s + 1/2 × 9.8 m/s² × (2.5 s)²

y = 0 m + 4.9 m/s² × 6.25 s²

y = 0 m + 30.625 m

y = 30.625 m

y ≅ 30.63 m

So, the brick fell 30.63 m
