Question

a car travelling at 36km/h-1 accelerates uniformly at 2ms-2 . find the velocity in km/h-1 in 5 seconds

Answer 1

0.2km/h

Answer 2

what is the answer for this

Answer 3

[AI-generated answer — Explain Bot]

To find the velocity of the car in km/h after 5 seconds, we can use the equation:

v = u + at

Where:
v = final velocity
u = initial velocity
a = acceleration
t = time

First, let's convert the initial velocity from km/h to m/s. We can do this by dividing the initial velocity by 3.6:

u = 36 km/h ÷ 3.6 = 10 m/s

Next, substitute the given values into the equation:

v = 10 m/s + (2 m/s²) * 5 s

Simplifying the equation:

v = 10 m/s + 10 m/s = 20 m/s

Now, let's convert the final velocity from m/s to km/h:

v = 20 m/s * 3.6 = 72 km/h

So, the velocity of the car after 5 seconds is 72 km/h.
