Two shuffleboard disks of equal mass, one orange and the other yellow, are involved in an elastic, glancing collision. the yellow disk is initially at rest and is struck by the orange disk moving with a speed of 4.80 m/s. after the collision, the orange disk moves along a direction that makes an angle of 36.0° with its initial direction of motion. the velocities of the two disks are perpendicular after the collision. determine the final speed of each disk.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

answerscientific theory;

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
