Answer with explanation

Answer with explanation angular speed in rad/s and in degree/s. A wheel has radius 30 cm. The wheel starts from rest and attains a speed of 300 r.p.m. in 3 minutes. What is its angular acceleration? What is angular displacement within this time? Calculate the angular velocity and linear velocity of a tip of minute hand of length 10 cm. An object of mass 100 g move around circumference of circle of radius 2 m with constant angular speed 7.5 rad/s. compute (a) Linear speed (b) Force directed towards centre Propeller blades in aeroplane are 2m long (a) When propeller is rotating at 1800 rev/min, compute the tangential velocity of tip of the blade. (b) What is the tangential velocity at a point on blade midway between tip and axis? The length of hour hand of a wrist watch is 1.5 cm. Find magnitude of following variables for a particle on tip of hour hand. (a) Angular velocity (b) Linear velocity (c) Angular acceleration (d) Radial acceleration e) Tangential acceleration A motor car is travelling at 60 m/s on a circular road of radius 1200 m. It is increasing its speed at the rate of 4 m/s2. The acceleration of the car is: If the equation for the displacement of a particle moving on a circular path is given by: 0=2t3 +0.5 where 9 is in radian and t in second, then the angular velocity of the particle at t = 2 sec is : P-11.2 car of mass 2000 kg rounds a curve of radii 50 m at 90 km/hr. Compute its, i) Angular speed
