An automobile travels on a straight road 35 km at 30 km/h. It then continues in the same direction for another 35 km at 60 km/hr. What is the average velocity of the car during the full 70 km trip? PLZ SHOW WORK.

Need in all of themmm only answer if you know plsssss

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

Consider the following position function. find (a) the velocity and the speed of the object and (b) the acceleration of the object. bold r left parenthesis t right parenthesisr(t)equals=left angle 6 t superscript 4 baseline comma 2 t cubed right angle6t4,2t3 for tgreater than or equals≥0
