System of Particles and Rotational Motion

Overview
In this video, we will cover:
1. A body of mass 0.4kg is attached to a string 1.2m long and then whirled round horizontally making 120 revolutions per minute. Find (a) Angular velocity (b) linear(c) normal acceleration
2. A cricketer can throw a ball to maximum horizontal distance 100m. How much high above the ground can the cricketer throw the same ball?
3. Rain is falling vertically with a speed of 35m/s. A woman rides a bicycle with a speed of 12 m/s in east to west direction. What is the direction in which she should hold her umbrella?
4. The velocities v1 and v2 of two objects are given by the vectors v1=3i^+4j^-4k^ and v2= 2i^-3j^-4k^. Where i, j and k are unit vectors. Find the vector for the relative velocity of the first object with respect to the second. What can you say about this vector?
5. A particle starts from origin t=0 with a velocity 5.0 ^i m/s and moves in x-y plane under action of a force which produces a constant acceleration of (3.0 ^i + 2.0^j) m/s2. (a) What is the y coordinate of the particle at the instant its x coordinate is 84m? (b)What is the speed of the particle at this time?
6. The position of a particle is given by r vector= 3ti-2t2j +4k m, where t is in seconds and the coefficients have proper units for r to be in metres. Find the velocity and acceleration of the particle at t= 2s.
7..A man swims heading right across a river for a length 0.6km in a certain time while the river flows 0.4 km in the same time.Find its resultant motion or change of position.
