I would like to know if you can break down step 2 part b
I know it has to do with some trigonometry, but how do you set up the equation? Like can you do a free body diagram, and explain a little bit more detail?
As shown in Figure 2, a small square mass m connected to a massless rod moves in a circle of radius r with constant velocity v. In the following, approximate the square mass m as a point mass.

- I need help with part c, can you write out the sentence with the answer please, thank you.arrow_forwardUse the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are v1i = +25.2 cm/s and v2i = −20.3 cm/s, what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.) v1f = v2f =arrow_forwardShow your solution. Two cars, 100 apart, are about to collide. The cars, X & Y, are running at constant speed of 60kph &80 kph, respectively. a.) Illustrate the velocity vectors of the cars and formulate the equations. b.) What is the speed (in kph) of car Y observed on car X? c.) How many seconds will they collide?arrow_forward
- During an elastic collision, a proton with a velocity of 5000 m/s (forward) undergoes a head on collision with an alpha particle (composed of two protons and two neutrons) with a velocity of 2000m/s (backward). Determine the final velocities of the subatomic particles. Assume forward is positive. Show all your work please.arrow_forwardInstruction: I already have the answer in this problem but I can't understand some part of it. Look at the image posted to see what part I can't understand and please explain it. I can't understand "Part B". How did he came up with the formula, h3=e2h2? Topic: Impulse and Momentum A ball is dropped onto a horizontal floor. It reaches a height of 144 cm on the first bounce, and 81 cm on the second bounce. Find (a) the coefficient of restitution between the ball and floor and (b) the height it attains on the third bounce.arrow_forwardBefore a collision, Cart A has 50 kg m/s of momentum and Cart B has -10 kg m/s momentum. Following the collision, Cart A has momentum of 30 kg m/s, Cart B is moving but you don’t know its momentum yet. What is the total momentum of the 2 car system before the explosion? Show your work.

- For part b, I do not really understand what the question is asking. During the 200 m trip upwards, to we have to consider that the elevator accelerates for 5 seconds, then decelarates for 5 secs and then moves with constant velocity? I do get the final answer that is 45 secs, but Ido not conceptually understand how I am supposed to understand that there is a period of decelaration during the upward motion. Could you please solve only part b and help me understand why both periods of acceleration and deceleration both need to be taken into consideration?arrow_forwardAnswer the following questions using the diagram from above. a) Which of the boxes in question 1 could be moving with a constant velocity?
