6. a) Hmax = 0.5*(g/6)*(t/2)2
Hmax = 0.5*1.63*4.252
Hmax = 14.7 m
b) v = (g/6)*(t/2)
v= 6.94 m/s

6. A tennis ball on Moon, where the acceleration due to gravity is 1/6 g (g- -9.8) and air resistance is negligible, is hit directly upward and returns to the same level 8.5 s later, (a) How high above its original point did the ball go? (b) How fast it moving just after it was hit?
7. Two train cars are on a straight, horizontal track. The car A starts at rest and is put in motion with a constant acceleration of 2.00 m/s2. This car A moves toward the car B that is 25.0 m away. The car B is moving in same direction as car A with an initial velocity of 4.5 m/s and is traveling with a constant acceleration of -1.50 m/s2 a) Where will the cars collide? b) How long will it...

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?
8). (15 points) Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.50 m/s2. This car moves toward a second car that is 32.0 m away. The second car is moving away from the first car and is traveling at a constant speed of 4.50 m/s. a) Where will the cars collide? b) How long will it take for the cars to collide?
2.39 A tennis ball on Mars, where the acceleration due to ma gravity is 0.379g and air resistance is negligible, is hit directly up- th ward and returns to the same level 8.5 s later. (a) How high above v its original point did the ball go? (b) How fast was it moving justi after it was hit? (c) Sketch graphs of the ball's vertical position, vertical velocity, and vertical acceleration as functions of time while it's in the Martian...
At the surface of the earth the acceleration due to gravity is 9.8 m/s2. How far above the surface of the earth would the acceleration due to gravity be 10% smaller? In other words, at what height is the acceleration due to gravity 8.82 m/s2?
an astronaut weighs 99N on the moon, where the acceleration of gravity is 1.62 m / s2. How much does the astronaut weigh on the earth?
Astronauts on our moon must function with an acceleration due to gravity of 0.170g . A. If an astronaut can throw a certain wrench 14.0 { m} vertically upward on earth, how high could he throw it on our moon if he gives it the same starting speed in both places? B. How much longer would it be in motion (going up and coming down) on the moon than on earth? ***For part A I got 82.4 m which is...
Show your work to get partial credit (26 points each) On the Moon, the acceleration due to gravity is -1.6 m/s^2 and there it no atmospheric drag. During the Apollo 14 mission, Alan Shepherd hit a golf ball on the Moon. Assume he hit the ball at an angle of 40 degree with an Initial velocity of 30 m/s. a. Find the total time the ball was above the ground, Assume it landed at the same height as it was...
