Sebuah mobil bergerak dengan perceparan tetap 5m/s^2. jika dalam waktu 4 detik jarak tempuh mobil tersebut 100m, kecepatan awal mobil tersebut adalah?

(a) 25 m/s
(b) 20 m/s
(c) 15 m/s
(d) 10 m/s
(e) 5 m/s

(E) 5 m/s

Explanation:

The question in english is:

A car moves with a fixed acceleration of . If within 4 seconds the mileage of the car is 100 m. What is the initial speed of the car?

We have the following data:

is the car's acceleration

is the time

is the distane the car has traveled

We need to find the car's initial velocity and this can be found with the following equation (assuming the car's initial position is ):

Isolating :

Hence, the correct option is (E).

the amount of current in the coil

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
