Q1)ship A is travelling with a velocity of 5km/h due east. the second ship is heading 30 degrees east of north. What should be the speed of the second ship if it is to remain always due north with respect to the 1st ship? 10km/h, 9km/h, 8 km/h, 7 km/h Q2) A man swims from a point A on one bank of a river of width 100m. When he swims perpendicular to the water current, he reaches the other bank 50m downstream. the angle to the bank at which he should swim to reach a point directly opposite pt. A is- 10 degrees upstream, 20 deg upstream, 30 deg upstream, 60 deg upstream

1. Explain path length and displacement with illustrations and distinguish them. 2. Define uniform velocity of an object moving along a straight line. What will be the shapes of position-time and velocity-time graphs of such a motion? Find the distance travelled by the uniformly accelerated object in one dimension in nth second. Draw velocity-time graph of a uniformly accelerated motion in one dimension and explain that the distance travelled is equal to the area under velocity-time graph. ted motion deduce the equations of motion in (i) From the velocity-time graph of uniform accelerated motion. velocity and time (ii) distance and time (iii) distance and velocity.
