A woman drives to her office 10 km away from her house at 9 am, and reaches her office at 9:20 am. She stays in the office until 6 p. m, and
then returns home at 6:25 p. m. Which answer gives the correct
distance and displacement at 6:25 p. m.?

Groups of organs that work together to complete a process in the body are called: a. cells b. tissues c. nerves d. systems

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

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
