Physics Question: An object of mass 2.00 kg is oscillating freely on a vertical spring with a period of 0.540 s. Another object of unknown mass on the same spring oscillates with a period of 1.11 s.
(a) Find the spring constant k. N/m
(b) Find the unknown mass. kg
The car collides and becomes stuck to a 5000kg truck travelling west at along South Street at the intersection of South Street and Murdoch Drive. Illustrate what is the final velocity of the vehicles after the collision if the truck was travelling..
An object placed on an equal-arm balance scale requires 12 kg to balance it. When object is placed on a spring scale, the spring scale reads 12 kg.
A 4.20 kg model rocket is launched, expelling 57.0 g of burned fuel from its exhaust at a speed of 675 m/s. What is the velocity of the rocket after fuel has burned.
What is the flux of Zn moving down the rod? Write down all your assumptions (hint: you will need to look up the density of copper. You do not need to account for the variation in density with alloy composition). Clarify what the boundary conditions w..
Illustrate what is the magnitude of the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center?
imagine a linebacker collides with a stationary quarterback and they become entangled. what will happen to the velocity of the linebacker-quarterback system if momentum is conserved.
Find out the translational speed at the bottom of the fall where it is horizontal. Ignore the frictional losses and assume mass of the cylinder is distributed uniformly.
What are the corresponding velocity vectors
Tim and Rick both can run at speed v_r and walk at speed v_w, with v_{rm r} > v_{rm w}. They set off together on a journey of distance D. Rick walks half of the distance and runs the other half. Tim walks half of the time and runs other half.
