A robot used in a pharmacy picks up a medicine bottle at t=0. It accelerates at 0.25 m/s2 for 6.5 s , then travels without acceleration for 57 s and finally decelerates at -0.60 m/s2 for 2.7 s to reach the counter where the pharmacist will take the medicine from the robot.

hey , the answer is c

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
