Question

A car is traveling with a certain speed. Its final velocity is 25m/s in 10s accelerating at the rate of 1.5m/s2.. Find the initial velocity of the car.

Answer 1

Answer:

10 m/s

Step-by-step explanation:

We can find the initial velocity by using Newton First Law Equation,

V = U + AT

Here, V = 25 m/s, A = 1.5 m/s^2, T = 10 sec.

Putting these values in the equation,

25 = U + 1.5 x 10

U = 25 - 15

Initial Velocity (U) = 10 m/s

Hope it helps..!!☺

Answer 2

Answer:

10m/s

Step-by-step explanation:

a = acceleration

v = final velocity

u = initial velocity

t = time taken

here,

a = (v - u)/t

1.5 = (25 - u)/10

1.5 × 10 = 25 - u

15 = 25 - u

15 - 25 = - u

- 10 = - u

both sides are negative so, negative sign gets cancelled

therefore, answer is 10m/s
