A 0.4 kg red ball is moving at 10 m/s along the positive x axis. The red ball elastically collides with a stationary blue ball. If after the collision the blue ball is traveling 7 m/s at 30 degrees from the x-axis, what is the red balls total velocity after the collision and in what direction? Please show work and I need to do this ASAP I’ll mark the first one brainliest

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
