Q1. A 1.14 kg air-track glider is attached to each end of the track by two coil springs. It takes a horizontal force of 0.500 N to displace the glider to a new equilibrium position, x= 0.130 m.
Find out the effective spring constant of the system.
The glider is now released from rest at x= 0.130 m. Find out the maximum x-acceleration of the glider.
Find out the x-coordinate of the glider at time t= 0.710T, where T is period of the oscillation.
Find out the kinetic energy of the glider at x=0.00 m.
Q2. A car is driven 125.0 km west and then 65.0 km southwest. What is the displacement of the car from the point of origin (magnitude and direction)?
At what angle is the curve banked? The acceleration due to gravity is 9.8 m/s2.
A ball has fallen to the street below, and a passerby returns it by launching it at an angle of 53.0° above the horizontal at a point 26.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall.
Suppose a constant ratio of 13.60 counts per minute per gram of living matter. A sample of a petrified tree was found to give 1.8 counts per minute per gram. How old is the tree.
Express how unmet basic physiological needs of oxygen, nutrition, temperature, and humidity threaten clients' safety.
An 11g bullet is fired into an 11kg wood block that is at rest on the wood table. The block, with the bullet embedded, slides 5.11 across the table. The coefficient of kinetic friction for wood sliding on wood is 0.25.
Where is center of mass of the system
After a tornado, a 0.55-g straw was found embedded 2.8 cm into the trunk of a tree. If the average force exerted on the straw by the tree was 70 N, what was speed of the straw when it hit the tree .
What is the decibel level required for human perception
How to find out an initial speed of the bullet
The electric field points radially outward at all points within the sphere (and outside too, for that matter). What is the strength of the electric field at a distance r from the center, inside sphere.
The speakers produce the same single-frequency tone in either drawing and are in phase. The speed of sound is 343 m/s. Find the single smallest frequency that would produce both constructive interference in drawing 1 and destructive interference in d..
Young's double-slit experiment is performed with 570 nm light and a distance of 2.00 m between the slits and the screen. The tenth interference minimum is observed 7.64 mm from the central maximum. Settle on the spacing of the slits.
