An astronaut standing on the surface of the moon throws a rock up into the air...

An astronaut standing on the surface of the moon throws a rock up into the air with an initial velocity of 8.617 m/s. When the rock is released, the astronaut’s hand is 1.16 m above the surface of the moon. (Acceleration due to gravity on the moon = 1.63 m/s2)
i) How long does it take for the rock to reach its maximum height?
ii) What is the rock’s maximum height?
iii) What is the time taken by the rock to move from astronaut’s hand to the surface of the
moon?
iv) Find the velocity of the rock when it touches the surface of the moon.

An astronaut stands on the surface of Vesta, which, with an average radius of 270 km, makes it the third largest object in the asteroid belt. The astronaut picks up a rock and drops it from a height of 1.4 m. He times the fall and finds that the rock strikes the ground after 3.4 s. (a) Determine the acceleration due to gravity at the surface of Vesta. m/s2 (b) Find the mass of Vesta. kg (c) If the astronaut...

A large catapult, standing on a flat field, throws a rock into the air with initial speed 17.8 m/s at an angle 33.1o to the horizontal. At the same time, there is a wind blowing parallel to the ground, causing the rock at accelerate at 0.703 m/s2 horizontally. Ignoring friction: find the horizontal distance, in m, that the rock travels before it hits the ground.

For a spherical celestial object of radius R, the acceleration due to gravity g at a distance x from the center of the object is g = g0R2/x2, where g0 is the acceleration due to gravity at the object's surface and x > R. For the moon, take g0 = 1.63 m/s2 and R = 3200 km. If a rock is released from rest at a height of 5R above the lunar surface, with what speed does the rock impact...

Romeo is standing 30 m (horizontally) from Juliet’s balcony, and he throws her a bouquet of flowers, tossing them with a speed of 20 m/s at an angle of 53.1° above horizontal. Juliet catches the flowers, inhales their fragran ce, and swoons. (The air, as ever, is unwilling to interfere with young love, so it offers no resistance to the motion of the flowers.) (a) Somewhere along their trajectory between Romeo and Juliet, the flowers will reach their maximum height....

An object is thrown vertically upward from the surface of Mars, where the acceleration due to gravity is ?1=3.70 m/s2.g1=3.70 m/s2. The initial velocity is ?1,v1, and the object reaches a maximum height of ?1.y1. What is the maximum height, ?2,y2, if the object is thrown with a speed of ?2=1.15?1v2=1.15v1 from the surface of Saturn's moon Rhea? The acceleration due to gravity on Rhea is ?2=0.264 m/s2.g2=0.264 m/s2. Give your answer as a multiple of ?1.

An astronaut is standing on the surface of a planetary satellite with no atmosphere that has a radius of 1.74 × 106 m and a mass of 7.35 × 1022 kg. An experiment is planned where a projectile needs to be launched straight up from the surface. What must be the minimum initial speed of the projectile, so it will reach a height of 2.55 × 106 m above this satellite’s surface? (G = 6.67 × 10-11 N ∙ m2/kg2)
