PLZ HELP, GIVING BRAINLIEST!! a cart initially traveling at 10 m/s to the right is accelerated uniformly at 2 m/s^2 to the right. how long will it take for the cart's speed to be 20 m/s?

Aturntable that spins at a constant 74.0 rpm takes 3.10 s to reach this angular speed after it is turned on. find its angular acceleration (in rad/s2), assuming it to be constant, and the number of degrees it turns through while speeding up.
