A 1200-kg pick-up truck traveling south at 15 m/s suddenly collides with a 750-kg car that is traveling east. The two vehicles stick together and slide along the road after colliding.
 
  A highway patrol officer investigating the accident determines that the final position of the wreckage after the collision is 25 m, at an angle of 50 south of east, from the point of impact. She also determines that the coefficient of kinetic friction between the tires and the road at that location was 0.40. What was the speed of the car just before the collision? A) 20 m/s
  B) 4.8 m/s
  C) 14 m/s
  D) 23 m/s
  E) 17 m/s

Question 2

At a location where g = 9.80 m/s2, a projectile returns to its original height after 4.08 seconds, during which time it travels 76.2 meters horizontally. If air resistance can be neglected, what was the projectile's initial speed?
 
  What will be an ideal response?
