An astronaut on a strange planet finds that she can jump a maximum horizontal distance of 16.0 m if her initial speed is 3.80 m/s. What is the free-fall acceleration on the planet? (Ignore air resistance.)
Suppose the vertical height h that Supergirl can jump after she compresses her tendons a distance x1 (beyond her unstretched length) is 25m. How high would she jump after she has compresses her tendons an additional 10% more than before (that is a distance 1.10x1 beyond her unstretched length)? A block of mass 3kg slides along a horizontal table with speed 10m/s. At x = 0 it hits a spring with spring constant 10N/m and begins to experience a friction...
An astronaut on the planet Zircon tosses a rock horizontally with a speed of 6.95 m/s . The rock falls through a vertical distance of 1.40 m and lands a horizontal distance of 8.80 m from the astronaut. What is the acceleration of gravity on Zircon? g=_____m/s^2
An alien visits Earth and discovers that she is able to jump incredibly high. The alien speculates that the free-fall acceleration g on Earth is different from that of her home planet. Her home planet is twice the diameter of Earth but made of material with the same density. In terms of g, what is the free-fall acceleration on the alien's home planet?
A) For the next scene, an astronaut travels to a moon of Planet W. She needs to measure the local gravity on the planet. She decides to use a 1.5 m long pendulum. She finds it takes her pendulum 6.09 seconds to complete one full oscillation. What is the acceleration due to gravity on this moon? a. 1.6 m/s2 b.2.1 m/s2 c. 2.3 m/s2 d.1.9 m/s2 B) For the next scene, an astronaut travels to a moon of Planet W....
An astronaut weighs 850 N on the Earth’s surface. When the astronaut lands on Planet X, she weighs 190 N. To the nearest tenth of a m/s2, what is the acceleration of gravity on Planet X? (hint: first find her mass!) An elevator car loaded with two passengers has a mass of 1200 kg. What tension must be applied by the elevator cable to give the car an acceleration of 1 m/s2 upward? Round your answer to the nearest newton....
1.A human expedition lands on an alien moon. One of the explorers is able to jump a maximum distance of 14.0 m with an initial speed of 2.90 m/s. Find the gravitational acceleration on the surface of the alien moon. Assume the planet has a negligible atmosphere. (Enter the magnitude in m/s2.)2.Two points in a plane have polar coordinates (2.00 m, 40.0°) and (3.70 m, 130.0°).(a) Determine the Cartesian coordinates of these points.(2.00 m, 40.0°)x = y=(3.70 m, 130.0°)x = y=(b) Determine the distance between them
Assume that the maximum horizontal distance you can throw a baseball (m = 0.145 kg) at an angle of α0 = 45∘ above the horizontal is 25 m. Part A) What is the kinetic energy of the baseball just after it leaves your hand? Ignore air resistance and the small distance the ball is above the ground when it leaves your hand. Take the zero of potential energy to be at the ground. Part B) At the ball's maximum height,...
During, the last s xx)nd (f ії; flight, ball thrown vertically upwards; covers one-half of the distance covered during the whole flight. The point of projection and the point of landing may or may not be in the same horizontal level. What maximum possible duration of the flight can be obtained? Neglect air resistance and assume acceleration of free fall to be 10 m/s2. Answer: 4 s During, the last s xx)nd (f ії; flight, ball thrown vertically upwards; covers...
(20 points) The horizontal and vertical components of the initial velocity of a golf ball are 60.4 m/s and 72.0 m/s respectively.
