A record spins at 33 rpm (revolutions per minute), which is an angular velocity of about 3.46 radians per second What is the approximate linear velocity of any that sts on the record 12 om from the center?

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.

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car
