Question

a car traveling with a soeed of 70 km/hr comes into rest in 0.5hrs. what will be the value of its redardation ​

Answer 1

Answer:

Retardation is 140 km/hr².

Explanation:

Given,

Initial Velocity (u) = 70 km/hr

Final Velocity (v) = 0 km/hr

Time (t) = 0.5 hr

Retardation = (u-v)/t

= (70-0)/0.5

= 70/0.5

= Retardation = 140 km/hr²

Hope this helps.
