2.2. 1 Driving at 36 m. s? (130 km. h ?) along a straight horizontal road (in a 90 km. h?i. e. 25 m. s zone), the driver sees a speed trap 69 m ahead. The driver's reaction time is one second i. e. it takes one second before the brakes are applied. The car then decelerates at 6 m. s2. Calculate the distance covered during the reaction time. ​

If the radius of curvature of the cornea is 0.75 cm when the eye is focusing on an object 36.0 cm from the cornea vertex and the indexes of refraction are as described before, what is the distance from the cornea vertex to the retina? express your answer to two significant

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
