A snowmobile is originally at the point with position vector 31.1 m at 95.0° counterclockwise from the x axis, moving with velocity 4.73 m/s at 40.0°. It moves with constant acceleration 1.84 m/s2 at 200°. After 5.00 s have elapsed, find the following. velocity vector position vector.
Brewed coffee is often too hot to drink right away. You can cool it with an ice cube, but this dilutes it. what is the final temperature of the coffee
A single conservative force F(x) acts on a 2.9 kg particle that moves along an x axis. The potential energy U(x) associated with F(x) is given by U(x) = -3.8xe^-x/5, What is the mechanical energy of the system
A 2.85 kg object is held in place on an inclined plane that makes an angle of 40 degrees with the horizontal. Calculate the initial acceleration of the system
A rock with mass m = 3.70 kg falls from rest in a viscous medium. The rock is acted on by a net constant downward force of F = 19.3 N and by a fluid resistance force.
A small rocket to gather weather data is launched straight up. few seconds into the flight, its velocity is 110 and it is accelerating at 17 . At this instant, the rocket's mass is 50 and it is losing mass at the rate of 0.45 as it burns fuel.
