Answer 1

$\huge{\underline{\mathtt{\red{❥A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

Answer:

Given that,

v = 20 m/s

u = 5 m/s

s = 50 m

We need to find : Acceleration (a) of the car.

Using the third equation of motion : v² - u² = 2as.

⇒ (10)² - (5)² = 2a*50

⇒ 100 - 25 = 100a

⇒ 75 = 100a

⇒ a = 75/100

⇒ a = 0.75 m/s²

Hence, Acceleration of the car is 0.75 m/s².
