Does the astronaut jumps higher on the Earth or on the Moon.

Question

Gab, a professional rooftop futbol player, kicked a 0.45 kg ball off a rooftop that is 81 m off the ground, at 15 m/s oriented 45° above his horizon. His pal, Henry, caught the ball from a window at a distant building that is 46 m off the ground. Henry then released the ball from this height and let the ball fall to the ground. A. What is the speed of the ball just before it reaches Henry? B. What is the speed of the ball just before it reaches the ground?

A roller coaster at the Six Flags Great America amusement park in Gurnee, Illinois, incorporates some clever design technology and some basic physics. Each vertical loop, instead of being circular, is shaped like a teardrop (as shwon). The cars ride on the inside of the loop at the top,and the speeds are fast enough to ensure the cars remain on the track. The biggest loop is 40.0 m high. Suppose the speed at the top of the loop is 13.0 m/s and the corresponding centripetal acceleration of the riders is 2g. (a) What is the radius of the arc of the teardrop at the top? (b) If the total mass of a car plus the riders is M, what force does the rail exert on the carat the top? (c) Suppose the roller coaster had a circular loop of radius 20.0 m. If the cars have the same speed, 13.0 m/s at the top, what is the centripetal acceleration of the riders at the top? (d) Comment on the normal force at the top in the situation described in part (c) and on the advantages of having teardrop-shaped…

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)?
