Q1. A spring with a spring constant of 2.0 × 102 N/m is attached to a 1.7 kg mass and then set in motion. What is the time of the mass-spring system?
Q2. A roller coaster, (h1 = 35 m, h2 = 12 m, h3 = 21 m), is pulled up to point A where it and its screaming occupants are released from rest. Assume no friction; compute the speed at points B, C and D.
Q3. A car takes 16 s to go from v = 0 to v = 50 m/s at approximately constant acceleration. If you wish to find the distance travelled using the equation d = 1/2 at2, what value should you use for a?
What is speed of the resulting ball of clay
What is frequency of the rotational motion for the wheel
A young boy swings a yo-yo horizontally above his head at an angular acceleration of 0.32 rad/s^2. If the tangential acceleration of the yo-yo at the end of the string is 0.15 m/s^2, how long is string.
What is the net electric flux through the spherical surface
Bob, of mass m, drops from a tree limb at the same time that Esther, also of mass m, begins her descent down a frictionless slide. If they both start at the same height above the ground, which is true about their kinetic energies as they reach the gr..
One displacement vector A has magnitude of 2.78 km and point due north. Another displacement vector B has a magnitude of 7.40 km and also points due north. Provide diagrams and calculate the magnitude and direction of A+B, B-A, A-B.
