1. Use conservation of momentum:MV+mv=0.imdiskid06 said:A small block of mass .5kg is released form rest at the top of a curved-shaped frictionless wedge of mass 3 kg , which sits on a frictionless horizontal surfces. When the block leaves the wedge, its velocity is 4 m/s to the right. Find the velocity of the wedge after the block reaches the horizontal surface. What is the height of the wedge?
That answers your question.Meir Achuz said:You may be so close to the bulb that it no longer looks like a point source.
That would be if distance were not large compared with the radius of the bulb.
Why is it 2mgH?Meir Achuz said:1. Use conservation of momentum:MV+mv=0.
2. Use conservation of energy:MV^2+mv^2=2mgH.
The velocity of a wedge after releasing a block can be calculated using the conservation of energy principle. The formula is v = √(2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height of the wedge.
The velocity of a wedge after releasing a block is affected by the height of the wedge, the mass of the block, and the angle at which the block is released. Other factors such as friction and air resistance may also play a role.
The height of a wedge after releasing a block can be calculated using the formula h = v2 / 2g, where h is the height, v is the velocity, and g is the acceleration due to gravity.
Yes, the velocity and height of a wedge after releasing a block can be determined experimentally by conducting a controlled experiment and measuring the relevant variables such as the height of the wedge, the mass of the block, and the angle of release. These values can then be used to calculate the velocity and height using the appropriate formulas.
The principles of finding velocity and height after releasing a block can be applied in various real-world scenarios such as calculating the trajectory of a projectile, determining the braking distance of a moving vehicle, and predicting the motion of objects in roller coasters. This information is also useful in engineering and design applications, such as designing ramps or calculating the impact force of falling objects.
