WebIf radius decreases then angular velocity or speed increases OK! Now if something was travelling at a speed v1 before decrease in radius and v2 after decrease in radius then we know v2>v1 right if no force was applied to it. so kinetic energy before was 1/2 mass v1^2 and after 1/2 mass v2^2 since v2>v1 kinetic energy after is greater than before.

WebFor this example the force–time graph could look like this. Notice the peak force is greater than the average force calculated. The area under a force time graph is equal to the … WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. WebWell hopefully, this second nature to you as well. But since opposite over hypotenuse is equal to the sine of 30. So VA in the y direction is equal to 2 times the sine of 30 degrees. The sine of 30 degrees is 1/2. So this is 1/2. 1/2 times 2 is equal to 1 meter per second. So after the collision, A is moving at 1 meter per second up. gale me kharash in english
