A car with a momentum of 1200 kg. m/s with a mass of 600 kg hit a trash can which was on the side of the road, If the mass of trash can is 7 kg and the velocity of the car after the collision was 10 m/s, what will be the final velocity of the trash can ? What kind of collision this one is? Explain,

What is a subatomic particle with a negative charge and very little mass?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s

When a pendulum is held high and taut and then is released, the pendulum begins to swing. what’s the correct order of the energy transformations in this example? (pe stands for potential energy.)
