It is acted upon by a constant force which produces a constant acceleration (4.0 iˆ + 4.0j) ms–2. What is the distance of the particle from the origin at time 2s? (a) 5m (b) 10√2m (c) 15 m (d)20√2 3.The coordinates of a moving particle at any time t are given by x=αt3 and y=βt3. The speed of the particle at time t is given by (a) √(α)2+( β)2 (b) √3tα+β2 (c) 3t2√α2+β2 (d) t2√α2+β2 4.A car goes around uniform circular track of radius R at a uniform speed v once in every T seconds. The magnitude of the centripetal acceleration is ac. If the car now goes uniformly around a larger circular track of radius 2R and experiences a centripetal acceleration of magnitude 8ac, then its time period is (a) 2T (b) 3T (c) T/2 (d) (3/2) T 5.The speed of a swimmer in still water is 20 m/s. The speed of river water is 10 m/s and is flowing due east. If he is standing on the south bank and wishes to cross the river along the shortest path the angle at which he should make his strokes w.r.t north is given by : (a) 30° west (b) 0° (c) 60° west (d) 45° west 6.A passenger arriving in a new town wishes to go from the station to a hotel located 10 km away on a straight road from the station. A dishonest cabman takes him along a circuitous path 23 km long and reaches the hotel in 28 min. What is (a) the average speed of the taxi, (b) the magnitude of average velocity? Are the two equal? 7.For angles of projection of a projectile at angle (45∘−θ) and (45∘+θ), the horizontal ranges described by the projectile are in the ratio of :(a) 1:1 (b) 2:3 (c) 1:2 (d) 2:1 8.The trajectory of projectile projected from the origin is given by the equation y=-2x2/5. The initial velocity of the projectile is a) 5 ms-1 b) 5/2 ms-1 c) 2/5 ms-1 d) 25 ms-1 9.The velocity of a projectile at the initial point I is (2i + 3j) m/s. It's velocity- (in m/s) at point B is (a) 2i - 3j (b) 2i+3j (c) -2+3j (d) -2i+3j 10.The velocity of a projectile, when it is at the greatest height, is √(2/5) times its velocity when it is at half of its greatest height. Determine the angle of projection? 11.An aircraft moving with a speed of 1000 km/h is at a height of 6000 m, just overhead of an anti-aircraft gun. If the muzzle velocity of the gun is 540 m/s, the firing angle θ for the bullet to hit the aircraft should be 12.A ball is thrown from ground at an angle θ with horizontal and with an initial speed u0. For the resulting projectile motion, the magnitude of average velocity of the ball up to the point when it hits the ground for the first time is V1.
