Question

answer the attached question​

Answer 1

Answer:

D) 4cm/s²

Explanation:

Concept :

Slope of Velocity VS Time graph gives us the acceleration

Therefore Acceleration = (y₂ - y₁) / (x₂ - x₁)

Max acceleration = more steep graph

Solution :

Most steep slope from B to C

(x₂ - x₁) given as 10

(y₂ - y₁) given as 40

∴ Acceleration = 40/10 = 4cm/s²

Here x₂,x₁,y₂, y₁ are nothing but the x and y coordinates of points B and C
