1. A bullet of mass 0.04kg moving with a speed of 90m/s enters a wooden block and is stopped after a distance of 60cm. What is the average resistive force exerted by the block on the bullet?

2. A projectile fired from the ground follows a parabolic path. At what position will the speed of projectile be minimum?

3. The driver of a three wheeler with a speed of 36km/h sees a child in the middle of the road and brings his vehicle to rest in 4s just in time to save the child. What is the average retarding force on the vehicle? The mass of the three-wheeler is 400kg and the mass of the driver is 65kg.

4. A train has to negotiate a curve of radius 400m. By how much should the putter rail be raised with respect to inner rail for speed of 48 km/h? The distance between the rails is 1m.

5. Find the magnitude of the centripetal acceleration of a particle on the tip of a fan blade, 0.30 metre in diameter, rotation at 1200 rev/minute
