In free space, a particle is projected from a point P on axis of a fixed rigid cone AOB, at an angle a = 37° with the axis (see figure). Distance of noint P from the apex O is x= 10 cm and the apex angle of the cone is B = 20°. All the collisions of the ball with the cone are perfectly elastic. (a) Find the distance of closest approach of the ball from the apex. Ans: x Sina-Gcm (6) How many times will the ball collide with the cone? P A

hi please solve this dof question
Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2. I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…

Question 20 Use basic drawing instruments (pencil, scale, protractor, compass, etc). The Front View of a line AB measures 65 mm and makes an angle of 45° with xy. A is in the H.P. and 15 mm in front of the V.P. The line is inclined at 30° to the V.P. Draw the projections of AB and find its true length and inclination with the H.P.
Question 16 Here is a way we can estimate the distance from the earth to the moon. When the moon is seen at its zenith at a point A on the earth, it is observed to be at the horizon from point B. Points A and B are 6152 miles apart and the radius of the earth is 3960 miles. 20 Earth 0= B a) Calculate the angle in radians. (Round your answer to 5 decimal places.) d= ? v Moon Details b) Estimate the distance from point A to the moon using your angle from part a). (Round your answer to the nearest thousand.) ?
