Question

(2) A toy car is moving at a speed of 20 meters per second. After covering a distance of one meter, the speed of this vehicle becomes 50 meters per second. Find the Acceleration of the vehicle.

Please help me
Not give bad answers please and describe please
​

Answer 1

Answer :

Initial speed = 20m/s

Final speed = 50m/s

Distance covered = 1m

We have to find acceleration of toy car$.$

Since, acceleration is said to be constant throughout the motion, we can easily apply third equation of kinematics to solve this question$.$

• v² - u² = 2as

Let's calculate ☃

➝ v² - u² = 2as

➝ 50² - 20² = 2a(1)

➝ 2500 - 400 = 2a

➝ 2100 = 2a

➝ a = 1050m/s²
