The average velocity is 8 km/hr

Further explanationThis problem is about Average Velocity.

Given:

The first displacement = d₁ = 10 km

Initial velocity = v₁ = 10 km/hr

The second displacement = d₂ = 2 km

Time taken for second displacement = t₂ = 30 mins = ¹/₂ hr

Asked:

Average velocity = v = ?

Formula:

Solution:

Firstly, we calculate the time taken for the first displacement:

Next, we could calculate the average velocity:

The average velocity is 8 km/hr

Rest

Explaination:

Rest is a state in physics that refers to an object being stationary relative to a particular frame of reference or another object; when the position of a body with respect to its surroundings does not change with time it is said to be "at rest".

Good Day

Problem:

Upton Chuck is riding the giant drop at Great America. If Upton free falls for 2.60 seconds, what will be his final velocity and how far will he fall?

Given Data:

Vi (initial velocity) = 0 m/s (at top)

Vf (final velocity) = unknown

t (time) = 2.60 seconds

a (acceleration) = 9.8 m/s²

Solution:

a= Vf-Vi/t, to solve Vf, we can use Vf = at +Vi

Vf = at +Vi

= 9.8 m/s² × 2.60 s + 0 m/s

= 25.48 m/s + 0 m/s

= 25.48 m/s

Solving for distance:

d = (Vf + Vi) / 2 × t

= 25.48 m/s / 2 × 2.60 s

= 33.124 m

Final velocity is 25.48 m/s

Distance = 33.124 m

3N = Newton

1.5 kg = Mass

Asked:

Acceleration = ?

Formula:

Acceleration = Force/Mass

Solution:

Acceleration = 3N/1.5kg

Acceleration = 2m/s^2

Final

The acceleration is 2 m/s^2.
