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...
1. A golf ball is hit with an initial velocity of 50.0 m/s at an angle of 34 degrees above the horizontal. If the golf ball lands on the same horizontal level, determine the time it takes the ball to stay in the air. 2. A ball is thrown horizontally, with a speed of 10 m/s, from the top of a 4.9 meter tall hill. How far from the point on the ground directly below the launch point does the...
In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 12 m/s at an angle of 20° above the horizontal (a) How long does it take for the ball to reach the wall if it is S.7 m away? (b) How high is the ball when it hits the wall?
In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 25 m/s at an angle of 34 ∘ above the horizontal. How long does it take for the ball to reach the wall if it is 3.7 m away? How high is the ball when it hits the wall?
In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 26 m/s at an angle of 34 ∘ above the horizontal. a) How long does it take for the ball to reach the wall if it is 3.3 m away? b) How high is the ball when it hits the wall?
In a friendly game of handball, you hit the ball essentially at ground level and send it toward a wall 22 m away with a speed of 20 m/s at 40 degree above the horizontal. a) Calculate the time for ball to strike wall. b) How high above the ground does the ball strike the wall? c) Find the speed of the ball at impact.
A golf ball is hit with an initial speed of 50.0 m/s with a
7-iron. If the ball left at 40.0 degrees and landed at a
point 50.0m lower than the initial position:
a)How long was the ball in the air?
b)How faraway will the ball land?
c) What is the maximum height with respect to the landing
point?
d)How long does it take for the ball to move ONLY a
distance
, on the horizontal, away
from where it...
Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 36.5 m/s at an angle of 31.0° above the horizontal. (a) Assuming that the a ands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. What constant acceleration equations will allow you to find the range, given the speed and angle? (Note that, depending on your...
On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 7 iron. The acceleration due to gravity on the moon is 1/6 of its value on earth. Suppose he hits the ball with a speed of 23.9 m/s at an angle 29° above the horizontal. How much farther did the ball travel on the moon than it would have on earth? For how much more time was the ball in flight?
On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 6 iron. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hits the ball with a speed of 14 m/s at an angle 25 ∘ above the horizontal. a) How much farther did the ball travel on the moon than it would have on earth? b) For how much more time was the ball in flight?
