ACTIVITY 2: Problem Solving (Uniform Accelerated Motion-Horizontal Dimension) 1. What is the final velocity of a race car traveling at 220 m/s accelerates at 30 m/s2 for a period of 17 seconds? GIVEN: FORMULA: SOLUTION: Vf= Vi+at FINAL ANSWER: 2. A Truck accelerates from 24.6 m/s to 52.33 m/s in 4.02 seconds. Calculate the distance travelled by the truck. GIVEN: FORMULA: SOLUTION: D= (Vf + Vi / 2) t FINAL ANSWER: ACTIVITY 3: Problem Solving (Uniform Accelerated Motion-Vertical Dimension) . 1. Suppose a free-fall ride at an amusement park starts at rest and is in free fall. a. What is the velocity of the ride after 2.3 s? b. How far do people on the ride fall during the whole period? SOLUTION: GIVEN: FORMULA: a. Vf= Vitat b. D=ViT + 1/2at FINAL ANSWER: ACTIVITY 4: Problem Solving (Projectile Motion) 1. A cannonball is launched horizontally from the top of a mountain with a velocity of 3.5 m/s. The cannonball falls 50 m away from the edge of the mountain. a) How high is the mountain? b) What is the cannonball's velocity just before it hits the ground? Given/Find: Horizontal (x) component (2 pts) |Vertical (y) component (3 pts) Vix = ay x Find: t = ? Solution: (6 pts)
