A cork shoots out of a champagne bottle at an angle of 36.0° above the horizontal. If the cork travels a horizontal distance of 1.30 m in 1.45 s, what was its initial speed?

A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure below. The length of the arc ABC is 260 m, and the car completes the turn in 40.0 s. I need to find the acceleration at a point 35 degrees below the horizontal in terms of vectors I...

A car starts from rest at a stop sign. It accelerates at 2.0 m/s2 for 6.0 seconds, coasts for 2.0 s, and then slows down at a rate of 1.5 m/s2 for the next stop sign. How far apart are The stop signs?

Hi.my questions are. 1-Are the instantaneous velocity vector and the acceleration vector always in the direction of the motion? Why? 2-is it possible for the velocity vector of a particle to be perpendicular to its position vector? Why? 3-is it possible for a particle to go around a curve at...

Someone is driving through a town at 12.0 m/s when suddenly a ball rolls out in front of them. You apply the brakes and begin decelerating at 3.5 m/s^2. a- How far do you travel before stopping? b- when you have traveled only half the distance in part (a), is the speed 6.0 m/s, greater than, or...
