1.
A point moves in the x-y plane according to the law x=3 cost and y = 3 (1-sin 40). The
distance travelled by the particle in 2 sec is (where x and y are in metres)
(1) 48 m
(2) 24 m

3. A body A starts from rest with an acceleration an. After 2 s, another body B starts from
rest with an acceleration az. If they travel equal distances in the fifth second, after the
start of A, then ratio aj:az is equal to
(1) 5:9
(2) 5:7
(3) 9:5
(4) 9:7
A body starts from rest with uniform acceleration a. Its velocity after n second is v. The
displacement of the body in last 3 s is assume total time of journey from 0 to n second)

A particle starts its motion from rest under the action of a constant force. If the distance
covered in first 10 seconds is S, and that covered in the first 20 seconds is S2, then
(1) S = 3S
(2) S2 = 45
(3) S2 = S
(4) S2 = 25
6. The equation of the path of the projectile is y = 0.5% - 0.04x'. The initial speed of the
projectile is
() 10 /
(2) 15 m/s
(3) 12.5 m/s
(4) None
1. A car is moving towards cast with a speed of 25 kmh. To the driver of the ear, a bus
