WebFeb 27, 2024 · Example 1: The speed of three cars are in the ratio 5 : 4 : 6. The ratio between the time taken by them to travel the same distance is. Solution: Ratio of time taken = ⅕ : ¼ : ⅙ = 12 : 15 : 10. Example 2: A truck covers a distance of 1200 km in 40 hours. WebRelative motion (speed) is covered at KS3 but not explicitly at KS4.

WebApr 8, 2024 · The time after which both bodies meet = distance traveled / relative speed. = dkm/ (x – y) km/hr. Now, we know that the relative speed is the speed of one object with respect to another. So, if time after which both the body moves is given, Suppose, time = t hrs. Then, distance covered in‘t’ hours = relative speed * time. Webω 2 = ω 0 2 + 2 α θ. v 2 = v 0 2 + 2 a x. v 2 = v 0 2 + 2 a x. constant. α. α, a. Table 6.3 Equations for Rotational Kinematics.
