- The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 2.20 m above the floor. The ball hits the floor 0.335 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 39.2 m/s^2 19.6 m/s^2 29.4 m/s^2 62.7 m/s^2A calculator may not be used on the following questions. A particle moves in the xy-plane so that its velocity vector for time 0 <<10 is (√36-67, 4t). Which one of the following statements is true about the particle when * = 1? Select one: a. The speed of the particle is √30 +4. O b. The particle is at rest. Oc. The particle is speeding up. Od. The particle is slowing down.In 2070, Adam wins a vacation at the new Moon Country Club. While vacationing Adam hits a golf ball off a cliff 300 meters high with an initial speed of 40 meters per second at an angle of 45° to the horizontal on the Moon(gravity on the Moon is one-sixth of that on Earth). Round all answers to three decimal places. a. Find parametric equations that describe the position of the ball as a function of time, t (round coefficients to three decimal places). b. How long is the ball in the air? c. When is the ball at its maximum height? What is that maximum height? d. When the ball lands, how far is it from Adam(the horizontal distance the ball traveled)?
- A baseball diamond is a square with side 90 ft. A batter hits the ball and runs toward first base with a speed of 24 ft/s. 90 ft (a) At what rate is his distance from second base decreasing when he is halfway to first base?

(Round your answer to one decimal place.) ft/sAn object's position in the as a function of time obeys the equation; x(t) = 14.2/t2.17 + 5.1t3 where all constants have proper SI Units. What is the speed of the object in the x direction at t = 1.93 seconds?A person throws a ball with speed 102 m/s at a 45° angle. How many seconds faster would the ball arrive if the person threw the ball at the same speed and the same distance but made the trip in two identical bumps. Assume that there is no loss of speed at the bounce. Hint: Use R = v2/g * sin(2θ) and t=2*vy(sinθ)/g.
