Discuss the validity of extrapolating the acceleration value to an angle of 90?
Extrapolate the experimental values of acceleration, vs. angle of the incline, to find the acceleration when the angle of inclination = 90 degrees. The acceleration at 90 degrees will equal 9.81 m/s/s, since this is the free-fall acceleration.
What is the the best catapult launch angle?
in a frictionless vacuum, 45°, otherwise (on earth), aim to have the projectile release when the arm is at about 40° from the base
What surface is 90 degrees to a horizontal surface?
Perpendicular
What does a inclined plane look like?
An inclined plane is just what its name suggests. It is an plane that is inclined (anlged) to be steep. To make an inclined plane, draw a right angle (90 degrees) and connect the two extended lines with a diagonal line. It should look like a triangle.
What angle for firing projectiles gives longest time?
45 degrees to the horizontal will give the maximum flight time for a projectile. If a projectile was fired at 90 degrees to the horizontal, (straight upwards) the projectile will go straight upwards (ignoring the shape, form and aerodynamic properties of the projectile). Likewise if you were to fire a projectile at 0 degrees to the horizontal, the projectile would follow said course, IF gravity was not in effect; a projectile needs some form of vertical velocity to overcome gravity. Hence why 45 degrees will give you the longest distance and consequently flight time.
A child slides down a frictionless slope at 25 degrees to the horizontal Calculate the child's acceleration down the slope?
a(child acceleration)=g(gravitational acceleration)*sin25=4.144 m/s2
A boy is tobogganing down a smooth slope inclined at 20 degrees to horizontal find his acceleration assuming resistances can be neglected?
sin20 = a/g a = gsin20 a = 3.35ms^-2
How do you resolve a horizontal force of 40 newtons into two perpendicular directions one of them inclines by 30 degree with the horizontal and upwards?
-- The component that's inclined 30 degrees above the horizontal is[ 20 sqrt(3) ] = about 34.641 newtons. (rounded)-- The other component is inclined 60 degrees below the horizontal,and its magnitude is 20 newtons.
What is Trajectory?
A trajectory is the angle made with the horizontal when a projectile is fired. Suppose the projectile is a cannon ball. Assuming air is frictionless, that cannon ball will travel the greatest distance if the trajectory is 45 degrees from horizontal.
What a step graph?
A graph which consists of short straight lines which keep changing direction. Example : a graph line which is inclined at say, 30 degrees to a horizontal, then changes direction instantly to a line which is say, inclined at 60 degrees to the horizontal , etc. If the shape of a graph is not a series of straight lines joined to each other, then it is not a step graph.
What is the acceleration of the 25 kg crate which is pulled by a rope along a frictionless surface at an angle of 30 degrees above the horizontal if the tension on the rope is 120 N?
the force acting down the slope = sin 30 * 25 (kg) = 0.5 * 25 = 12.5 kg = (12.5 * 9.806 ) 122.575 newtons = resultant force of (122.575-120 ) 2.575 newtons downhill giving downhill acceleration of (using f=ma) 0.103 (m/s)/s
A plane inclined at an angle 35 degrees from horizontal if the coefficient of static friction between the crate and the plane is 0.65 will the crate slide down the plane?
Is mgsinΘ > μmgcosΘ ? Is sinΘ > μ cosΘ ? Is sin35º > .65 cos35º Is .573 > .532 => Yes, so crate slides down the plane, no matter what the mass is or acceleration due to gravity
What is the minimum force required to prevent a ball weighing 12 lbs from rolling down a ramp which is inclined 60 degrees with a horizontal?
12 x sin 60 = 11.08 pounds
What is The earths axis is inclined at?
23.5 degrees.
How many degrees is mars axis inclined from its vertical plane?
it is about 23 degrees
What is Jupiter's axis tilt?
Axes aren't inclined, they are tilted. Orbital planes are inclined, and Jupiter's is inclined about 6 degrees from the Solar equator. Planes can also be inclined relative to the ecliptic or the invariable plane. Jupiter's axis is tilted about 3 degrees from the ecliptic.
Are there degrees of acceleration of a tornado?
Yes
