- Where is the magnetic field the strongest?How can you tell? square
- A firework rocket starts from rest at ground level and moves vertically. In the first 3s of its motion, the rocket rises 27 m . The rocket is modelled as a particle moving with constant acceleration 6ms^-2 Find the speed of the rocket 3 s after it has left the ground.
- A man throws a tennis ball into the air so that, at the instant when the ball leaves his hand, the ball is 2 m above the ground and is moving vertically upwards with speed 9ms^-1 The motion of the ball is modelled as that of a particle moving freely under gravity and the acceleration due to gravity is modelled as being of constant magnitude 10ms^-2 The ball hits the ground T seconds after leaving the man's hand. Using the model , find the value of T. (4 marks) T= seconds
- Fossil Fuels:Question 6 When a fossil fuel is combusted for electricity.what is the immediate next step? Select one: Carbon dioxide is absorbed by the fossil fuel A generator converts kinetic energy to electrical energy Water is heated and steam is produced A turbine is turned
- A particle, of mass 400 grams, is initially at rest at the point O. The particle starts to move in a straight line so that its velocity, vms^-1 at time I seconds is given by v=6t^2-12t^3 for tgt 0 (a) Find an expression in terms of I for the force acting on the particle. (b) Find the time when the particle next passes through O. (3) (5)
