Define muzzle velocity physics7/25/2023 ![]() The motion of falling objects, as covered in Chapter 2.6 Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no horizontal movement. The object is called a projectile, and its path is called its trajectory. ![]() ![]() Projectile motion is the motionof an object thrown or projected into the air, subject to only the acceleration of gravity. Apply the principle of independence of motion to solve projectile motion problems.Determine the location and velocity of a projectile at different points in its trajectory.Identify and explain the properties of a projectile, such as acceleration due to gravity, range, maximum height, and trajectory.Calculate the force needed to bring the car to rest over a distance of 20 m.(3mks) A car of mass 800 kg is initially moving at 25 m/s.This is because the can tends to remain in its state of rest.Tendency of a body to remain in its state of rest or in uniform motion unless acted upon by an external force.Determine the refractive index of a ray of light moving from water to glass. The refractive indices of water and glass are 4/3 and 3/2 respectively.Normal ray, incident ray and refracted ray all lie on the same plane Reflection refers to the bouncing of light when it strikes bright surface while refraction refers to the bending of light at the interface as it travels from one medium to another.Acceleration of the body over interval AE.Packing maize high up raises the c.o.g making the lorry unstable.Explain why a lorry loaded with bags of maize packed high up is likely topple over when negotiating a corner.(2mks).Given that the standard atmospheric pressure is 76cmHg and the density of mercury is 13600kg/m 3, determine the altitude of the town. The barometric height of a certain town is 65cmHg.In x adhesive forces are stronger than the cohesive forces while in y, the cohesive forces are stronger than the adhesive forces.is a force that makes the surface of a liquid to behave like a thin elastic stretched skin.calculate the recoil velocity of the gun.( 3mks) If the muzzle velocity of the bullet is 300m/s. A bullet of mass 0.006kg is fired from a gun of mass 0.5kg.Calculate the force needed to bring the car to rest over a distance of 20m.(3mks) A car of mass 800 kg is initially moving at 25m/s.When the card is horizontally pulled away suddenly, the coin drops in the can. The figure below shows a smooth card placed on the open end of a car.Use it to calculate the refractive index of glass. The graph shown below shows, the apparent depth (y-axis) against real depth.Given that the speed of light in air 3.0 x 10 8 m/s, find the speed of light in glass (2mks).Given that the critical angle for glass is 42° determine ![]() A ray of light makes a glancing angle of incidence i = 60° with a flat glass surface as shown in figure.State the two laws of refraction of light(2mk).Distinguish between reflection and refraction of light (1mk).Acceleration of the body over interval AE (2mk).Velocities between points AB and DE (3mk).The time taken for one tick interval (1mk).Figure below shows a tape made from a ticker tape timer running at 50Hz.Explain why a lorry loaded with bags of maize packed high up is likely topple over when negotiating a corner.The figure below shows a uniform metal rod balanced at the centre by different forces.The minimum pressure it exerts on the surface.A block measuring 20cm by 10cm by 4cm rests on a flat surface.Calculate the density of liquid K in SI units. Its mass is 100g when filled with water and 120g when filled with liquid K. An empty density bottle has a mass of 50g.The diagram below shows drop of liquids X and Y carefully put on a clean flat glass slab.
