Question: A particle has initial velocity 5 m/s due east and acceleration 2 m/s^2 due west. Find the distance traveled during 3rd second of the motion.
Is the collision completely elastic
What is the magnitude and direction of the magnetic field
The 2.00 kg object below is released from rest at the height of 5.0 m on a curved frictionless ramp. At the foot of the ramp is a spring of force constant k = 450 N/m. The object slides down the ramp and into the spring, compressing it a distance x b..
Find out the coefficient of sliding friction
A kayaker needs to paddle north across a 200 wide harbor. The tide is going out, creating a tidal current that flows east at 2.0. The kayaker can paddle with a speed of 3.0. In which direction must he paddle in order to travel straight across the har..
If a disco disk is rotating with a person on it on the outer side, then if he moves inside (towards the center), the angular velocity will change-How will the energy be conserved.
Use the simulation in the cannon interactive in this section to answer the following questions. (a) Does cannonball's horizontal velocity change as it moves through the air? (b) Does its vertical velocity change? (c) If you enhance the cannonball's h..
A 0.255 kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.200 kg puck that is initially moving along the x axis with a velocity of 2.06 m/s. After the collision, the 0.200 kg puck has the speed of 1.02 m/s at an ang..
A box of books weighing 397 N is shoved across the floor by a force of 543 N exerted downward at an angle of 37 degrees below the horizontal.
Two long, parallel conductors carry currents I1 = 3.10 A and I2 = 5.10 A, both directed into the plane of the computer screen. Find out the magnitude and direction of the resultant magnetic field at a point midway between the wires. (b) Find out the ..
