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)?
What is the horizontal distance x to the base of the wall supporting the mirror of the near point on the floor that can be seen reflected in the mirror . What is the speed of the third fragment? Overlook effects due to gravity.
The latent heat of fusion
A uniform plank of length 5.8m and weight 229N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 450N walk on the overhanging part of the plank be..
Illustrates the difference between acceleration and velocity
When subject to a steady acceleration of 0.800 g, the object must be located 0.600cm from its equilibrium position. Find the force constant required for the spring.
What are magnitude and direction of the force
Water flows through a pipe with circular cross section. The fluid has a radius of 5.0 cm and flows at 2.0m/s. The output has a radius of 2.50 cm. find the output velocity.
How much does the rocket clear the top of the wall
Which vector has the largest x component and y component
Some athletes can put out as much as 800 watts in short bursts. If you could sustain such energy output long enough to reach the top of a mountain, how much time would it take you to get there from the valley, 3000 meters below the peak? So how does ..
At the factory, a noon whistle is sounding with the frequency of 464 Hz. As a car travelling at 76 km/h approaches the factory, driver hears the whistle at frequency fi. After driving past the factory, the driver hears frequency ff. What is the chang..
A small ball of mass 62 g is suspended from a string of length 37 cm and whirled in a circle lying in the horizontal plane. If the string makes an angle of 33? with the perpendicular, find the centripetal force experienced by the ball. The accelerati..
