14. A monkey standing on the ground wants to climb to the top of a vertical pole of \( 15 m \). He climbs \( 5 m \) in \( 1 s \) and slips downward \( 3 m \) in next second. He again climbs \( 5 m \) in \( 1 s \) and slips by \( 3 m \) in the nexd second and so on. The time taken by the monkey to climb at the top of pole is a. \( 2 s \) b. \( 3 s \) c. \( 9 s \) d. \( 11 s \)

0. A car starting from rest has a constant acceleration \( a_{1} \) for time interval \( t_{1} \) and then constant retardation \( a_{2} \) for next time interval \( t_{2} \) and comes to rest. The average velocity of car during the whole motion is: (A) \( \quad \frac{a_{1} a_{2}\left(t_{1}+t_{2}\right)}{a_{1}+a_{2}} \) (B) \( \quad \frac{a_{1} a_{2}\left(t_{1}+t_{2}\right)}{2\left(a_{1}+a_{2}\right)} \) (C) \( \frac{a_{1} a_{2}\left(t_{1}+t_{2}\right)}{3\left(a_{1}+a_{2}\right)} \) (D) \( \frac{a_{1} a_{2}\left(t_{1}+t_{2}\right)}{4\left(a_{1}+a_{2}\right)} \)

A particle of mass \( 0.5 kg \) is projected with a speed of \( 20 m / s \) at an angle of \( 60^{\circ} \) with the horizontal. A bird observes the trajectory of the particle and follows exactly the same path with a constant speed of \( 5 m / s \). The force exerted by air on the bird at the highest point will be (neglect air resistance on particle) \( 5= \) \( \left( g =10 m / s ^{2}\right) \) (1) zero (2) \( 2.5 N \) (3) \( 5 N \) (4) \( 10 N \)
