On Mars, where the acceleration due to gravity is 3.8 m/s2, a 500 gram ball is thrown from a cliff that is 30 m above the ground at a speed of 22 m/s. The ball lands 45 m away from the base of the cliff. What is the speed of the ball just before it hits the ground?

A ball is thrown horizontally from the top of a 25 m vertical cliff and lands 101 m from the base of the cliff? what is the speed of the ball just before it hits the ground?
A tennis ball on Mars, where the acceleration due to gravity is 0.379 of a g and air resistance is negligible, is hit directly upward and returns to the same level 9.20 {\rm s} later. How high above its original point did the ball go? and How fast was it moving just after being hit?
A ball is thrown horizontally from the top of a 57 m vertical cliff and lands 92 m from the base of the cliff. What is the vertical component of the velocity of the ball just before it hits the ground?
A 2.7-kg ball is thrown upward with an initial speed of 20.0 m/s from the edge of a 45.0 m high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.00 m/s. The woman runs in a straight line on level ground, and air resistance acting on the ball can be ignored. 1.At what angle above the horizontal should the ball be thrown so that...
6. An astronaut ona distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +15 m/s and measures a time of 20.0 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? See Diagram below: 20.0s v,15 m/s Show your work below: 7. Problem using vectors: A sailboat sails for 1 hr at 4 km/hr (relative to the...
A red ball is thrown down with an initial speed of 1.3 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. What is the speed of the...
Onur drops a basketball from a height of 10 m on Mars, where the acceleration due to gravity has a magnitude of 3.7 . We want to know how many seconds the basketball is in the air before it hits the ground. We can ignore air resistance. Which kinematic formula would be most useful to solve for the target unknown? Choose 1 answer: 2
On Mars, the acceleration due to gravity is 3.71 m/s2. How far would a rock fall in [Number 6.01] s if you dropped it on Mars?
A red ball is thrown down with an initial speed of 1.2 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.8 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. 1) What is the speed of...
