Question

car drivet increases speed of a car at 10 m /s for 5 seconds.. find maximum velocity if its initial velocity is 10 m/s​

Answer 1

Answer:

per second increase in speed = 10 m/s

time while the process is being done = 5 s

initial velocity = 10 m/s

Explanation:

10m/s(initial velocity)+(5s(time) × 10m/s(increasing velocity per second) )

= 10 + 50

= 60metres per second will be the maximum velocity.

hope this helps.

have a great day.

Answer 2

Given :-

Acceleration of the car = 10 m/s²

Time taken by the car = 5 sec

Initial velocity of the car = 10 m/s

To Find :-

The maximum velocity of the car.

Analysis :-

Here we are given with the acceleration, time and initial velocity of the car.

In order to find the maximum velocity of the car substitute the given values from the question in the first equation of motion.

Solution :-

We know that,

• t = Time
• a = Acceleration
• u = Initial velocity
• v = Final velocity

Using the formula,

$\underline{\boxed{\sf First \ equation \ of \ motion=v=u+at}}$

Given that,

Initial velocity (u) = 10 m/s

Acceleration (a) = 10 m/s²

Time (t) = 5 sec

Substituting their values,

⇒ v = 10 + (10 × 5)

⇒ v = 10 + 50

⇒ v = 60 m/s

Therefore, the maximum velocity of the car is 60 m/s.
