Question

pls anyone solve this... urgent​

Answer 1

u=0m/s

v=80m/s

t=8s

a=?

a=v-u/t

a=80-0/8

a=80/8

a=10m/s

Answer 2

buddy, take the slope of the graph shown

Let's take the points (2, 60) and (4, 40)

So, this makes our x₁ = 2, x₂ = 4, y₁ = 60 and y₂ = 40

the formula of slope is: y₂ - y₁/x₂ - x₁

= 40 - 60/4 - 2 = -20/2 = -10 m s⁻²

Since the acceleration is negative, we can also call it as retardation
