A block of mass M is at rest on a frictionless horizontal surface and is attached to a spring of spring constant k as shown in the figure. Another block of mass M is pushed towards the first block with speed The two blocks collide and stick together and the system begins to oscillate.
Find the speed of the two blocks immediately after the collision.
How long will it take for the two blocks to return to the original position?
Find the amplitude of the oscillating system.
How many 111 W lightbulbs can you use in a 107 V circuit without tripping a 16 A circuit breaker? (The bulbs are connected in parallel, that means that the potential difference across each lightbulb is 107 V.)
A vehicle is traveling at 7.0 m/s when the driver applies the brakes. compute how far would it have continued to move after the brakes were applied
An air bubble has a volume of 1.80 cm3 when it is released by a submarine 120 m below the surface of a lake. Find the force exerted by the gas on one of the walls of the container
After the second exam, your evil instructor is finally thrown upinto the air at the edge of a cliff with a velocity of 7.50m/s. With what velocity does he hit the ground if he justmisses the edge of the cliff and lands 30.0m below his launchpoint? Ig..
A circular conducting loop carries a current of 5.0 A and has radius 30 mm, Calculate the magnetic field at the centre of the loop (H) How many turns would be needed to give a field of 1.0 mT
In a game of basketball, a forward makes a bounce pass to thecenter. The ball is thrown with an initial speed of 4.8 m/s at an angle of 14.2° below the horizontal. It isreleased 0.67 m above the floor. What horizontal distance does the ball cover ..
To measure the speed of a bullet, the following situation is setup. A wooden block(m=0.50kg) is put on top of a fencepostwith a height of 1.5m. The bullet (m=.010kg) strikes theblock from a perfectly horizontal direction and remains embedded init. Th..
