sics 101 SICS 0780938042 Aljall saal R1) An object has a position given by r = [2+3t)i+ [3- 2t21j. What is the peed of the object at time t = 1s ? A) 4 m/s B) 10 m/s C) 5 m/s D) 8 m/s R2) A projectile is fired from ground with an initial velocity v = 30i + Oj m/s and returns to the ground. Find the horizontal range of the rojectile. A) 60 m B) 30 m C) 120 m D) 40 m 23) At t = 0, a particle leaves the origin with a velocity of 10 m/s in the ositive y direction and moves in the xy plane with a constant acceleration f (2i - 4j) m/s2. At the instant the x coordinate of the particle is 25 m, Vhat is the speed of the particle ?
