##### Owen and Dina are at rest in frame $\mathrm{S}^{\prime}$ , which is moving with a speed of 0.600$c$ with respect to frame $\mathrm{S}$ . They play a game of catch while Ed, at rest in frame $\mathrm{S}$ , watches the action (Fig. P26.45) . Owen throws the ball to Dina with a speed of 0.800 $c$ (according to Owen) and their separation (measured in $\mathrm{S}^{\prime} )$ is equal to $1.80 \times 10^{12} \mathrm{m} .$ (a) According to Dina, how fast is the ball moving? (b) According to Dina, what
