Answer:
The instantaneous velocity at any time during the second hour of the trip is 60 mph east
(C) is correct option
Explanation:
Given that,
Distance in first hour = 25 miles
Distance in second on hour = 60 miles
Instantaneous velocity :
Instantaneous velocity is equal to the distance divided by the time
We need to calculate the instantaneous velocity at any time during the second hour of the trip
Using formula of instantaneous velocity
.[tex]v = \dfrac{d}{t}[/tex]
Where, d = distance
t = time
Put the value into the formula
[tex]v = \dfrac{60}{1}[/tex]
[tex]v= 60\ miles/hr[/tex]
The direction of the instantaneous velocity is in east .
Hence, The instantaneous velocity at any time during the second hour of the trip is 60 mph east
The instantaneous velocity at any time during the second hour of the trip is 60 mph east.
Instantaneous velocity is the rate of change of position for a time interval. The instantaneous velocity is the velocity at a particular time.
Instantaneous Velocity Formula of the given body at any specific instant can be formulated as:
- V₁ = δx / δt
- V₁ = Δx / Δt
where
Δx = change in position
Δt = small time interval
During the second hour of the trip, the instantaneous velocity at that particular time is
- 60 / 1 = 60 mph east
The instantaneous velocity = 60 mph east
