if an 8kg mass is pulled up an incline at a constant speed, determine a. the tension in there is no friction between the cord and the pulley​

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

Choose each of the settings that follow and list them below do it ill mark brainliest first object= position= speed= acceleration= second object= position= speed= acceleration=

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects
