Question

A scooterist moving on a straight highway at 54 km/ h, sights obstacle at a distance at a distance pf 50 m, and applies to produce -2.5 m/sec^2 the retardation. Will he be able to avoid the accident?​

Answer 1

☑ Required Answer-

Velocity of A ⇒54km/hr⇒15m/s.

Since the motion of B is seen in perpendicular direction by A.

∴ Its component of velocity will be 15 m/s in the direction of motion of A in same direction. Now Its velocity is 5 m/s in perpendicular direction .

∴ Magnitude of velocity ⇒√5square+15square ⇒√250 ⇒5√10 m/s at some angle away from the car.
