The identical twins speedo and gosto join a migration from the earth to planet x, 19.5 ly away in a reference frame in which both planets are at rest. the twins, of the same age, depart at the same momento different spacecraft. speedo's spacecraft travels steadily at 0.930c and goslo's at 0.715c. (a) calculate the age difference between the twins after goslo's spacecraft lands on planet x 5434 x your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation carry out all intermediate results to at least four digit accuracy to minimize roundoff error. y (b) which twin is older?

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
