A cannon is shot downwards with an initial speed of 10m/s at an angle of 20 degrees South of East off a 60m cliff. Find the initial velocity in the y-direction.

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving
