... A boat moves through the water with two forces acting on it. One is a 2000-N forward push by the water on the propeller, and the other is an 1800-N resistive force due to the water around the bow. (a) What is the acceleration of the 1000-kg boat? (b) If it starts from rest, how far will it move in 1 ...

... In a galaxy far far away there is a small, strange planet shaped like a cone. This planet has mass M , base radius R, opening angle α and it rotates about its axis with an angular velocity ω. A spherical alien of mass m << M and radius h lands on the planet, a distance ρ >> h from its axis. a) At wh ...

Newtons laws
... Mass is directly related to inertia. • The greater the mass the greater the tendency to resist change of an object’s motion. • objects will continue to do as they are doing with out friction. ...

... (E) Both cannons B and C have the greatest range 35. A punter in a football game kicks the ball with an initial speed of 28.3 m/s at an angle of 60° with respect to the ground. The ball is in the air for a total of 5.00 s before hitting the ground. If we assume that air resistance is negligible, wha ...

... First Law: If the net force exerted on an object is zero the object continues in its original state of motion; if it was at rest, it remains at rest. If it was moving with a certain velocity, it will keep on moving with the same velocity. Second Law: The acceleration of an object is proportional ...
