2 persons a and b are working with speed 4km/hr and 5 km/hr in the same directions. Find how far will be b from a after 3 hours?
Asked by PriyaAnk ShaRma | 24 Sep, 2013, 11:56: AM
Person a:
Distance da = vt = 4 km/h × 3 h = 12 km

Person b:
Distance db = vt = 5 km/h × 3 h = 15 km

Thus, b will be 3 km away from a after 3 hours.

Important derivations:
1) To derive the three kinematical equations.

2) To derive the equation of path of projectile.

3) To derive time of flight of a projectile, and also maximum height reached and horizontal range of projectile.

4) Maximum speed of a vehicle on a banked road.

5) Derive the work energy theorem for a variable force.

6) Expression of speed of two particles after elastic collision between the two.
