Question

a) A car decreases its speed from 80 kmh -1 to 60 kmh -1 in 5s, find the acceleration of the car. b) Derive an equation for position-time relation for an object that traveled a distance 's' in time 't' under uniform acceleration 'a'.

Answer 1

$\boxed{\bf{\blue{\longrightarrow Answer:}}}$

• Acc. =
• $\frac{60 - 80}{ \frac{1}{12} }$
• $= - 20 \times 12 = - 240$
