At a particular moment, a student needs to stop his speedy bike to avoid a collision with the barrier ahead at a distance 40 meters away from him. Immediately he slows (retardation) the bike under braking at a rate of `8 "metre/second"^2`. If the bike is moving at a speed of 24 m/s, when the brakes are applied, would it stop before collision?

At a particular moment, a student needs to stop his speedy bike to avoid a collision with the barrier ahead at a distance 40 meters away from him. Immediately he shows (ratardation) the bike under braking at a rate of 8 "metre"//"second"^(2) . If the bike is moving at a speed of 24 m/s, when the brakes are applied, would it stop before collision?

A cyclist moving on a level road at 4 m/s stops pedalling and lets the wheels come to rest. The retardation of the cycle has two components: a constant 0.08 m//s^2 due to friction in the working parts and a resistance of 0. 02v^2//m , where v is speed in meters per second. What distance is traversed by the cycle before it comes to rest? (consider 1n 5=1.61).

A boy riding on his bike is going towards east at a speed of 4sqrt2ms^-1 . At a certain point he produces a sound pulse of frequency 1650 Hz that travels in air at a speed of 334 m s^-1 . A second boy stands on the ground 45^@ south of east from him. Find the frequency of the pulse as received by the second boy.
