PartA Constants If the flare is fired at an angle of 48.0° above the horizontal on the level salt flats of Utah, what is its horizontal range? You can ignore air resistance A pistol that fires a signal flare gives the flare an initial speed (muzzle speed) of 150 m/s ΑΣφ km Submit ▼PartB If the flare is fired at the same angle over the flat Sea of Tranquility on the moon, where g 1.6m/s, what is its horizontal range?...
A block is on a frictionless horizontal table, on earth. This block accelerates at 4.6 m/s2 when a 30 N horizontal force is applied to it. The block and table are then set up on the moon where the acceleration due to gravity is 1.62 m/s2. A horizontal force of 15 N is applied to the block when it is on the moon. What acceleration does this force impart to the block? A block is on a frictionless horizontal table,...
A horizontal launch took place on the moon where the gravitational acceleration is 1/6 that of earth. If the horizontal range were the same how must the initial velocity of the ball compare?
Jim throws a ball at an angle of 45° above the horizontal with a range of 40.0 m. If Jim instead throws the ball straight upward, what maximum height will the ball reach above its release point?
An arrow is shot at an angle of ?=45? above the horizontal. The arrow hits a tree a horizontal distance D=220m away, at the same height above the ground as it was shot. Use g=9.8m/s2 for the magnitude of the acceleration due to gravity. Suppose someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree. How long after the arrow was shot should the apple be dropped, in order...
The force of gravity exerted by Earth on a fully suited astronaut at Earth's surface is 1810 N . What is the magnitude of the gravitational force exerted on her on Jupiter, where the acceleration due to gravity is 25.9 m/s2. What is the magnitude of the gravitational force exerted on her on the Moon, where the acceleration due to gravity is 1.6 m/s2?
Find the range of a football(when it launches at 45 degrees above the horizontal), neglecting air resistance. Express your answer in terms of launching speed of the football v, and its acceleration due to gravity g.
An arrow is shot at an angle of @= 45° above the horizontal. The arrow hits a tree a horizontal distance D = 220 m away, at the same height above the ground as it was shot. Use g = 9.8 m/s for the magnitude of the acceleration due to gravity. Part A Find ta, the time that the arrow spends in the air. Answer numerically in seconds, to two significant figures.

A The Earth exerts a gravitational pull of 2.0 ×1020 N on the Moon; the Sun exerts a gravitational pull of 4.3 ×1020 N on the Moon.What is the net force on the Moon when the angular separation between the Earth and the Sun is 90 as seen from the Moon? B : A gun on the shore (at sea level) fires a shot at a ship which is heading directly toward the gun at a speed of 40 km/h....
Sally and David are runners participating in a relay race. Sally runs at a constant speed of 2.0 m/s. When she is 1.8 m behind David, he starts from rest and begins to run in the same direction as Sally with a constant acceleration of 0.5 m/s^2. When Sally reaches him, she hands him the baton. a) (20 points) How far has David run when he gets the baton? b) (5 points) What is David’s speed at the moment he...
