dist d : 160 ) (2 ) A. A car is traveling at 60 km/hr for 2.0 hours. How far did the car travel? 120 km 30 kma 62 kun Speed in a given direction is known as velocity. True or False . Acceleration is the rate of change of velocity. (True or False 30 A car is accelerating at 4.0 km/hr/sec. This means that for every 1 hour of time, the car's velocity is increasing by 4.0 km/sec. True or False 31, A car is decelerating at 3.0 km/hr/min. This means that for every 1 minute of time, the car's velocity is decreasing by 3.0 km/hr. True or False Acceleration can involve a change in speed, a change in direction, or a change in speed and direction. True or False A car traveling at 30 km/lhr increases it's velocity to 60 km/hr in 2 minutes. Its acceleration is: a. 15 km/har/min 30 / 2 - 13 45 kma/lar/main The acceleration due to gravity on the Earth is 9.8 m/s/s. True or False OK You are standing on a bridge. You are holding a rock that you drop vertically downward. How far did the rock fall in 2 seconds? 78.4 m 19.6 m (9: 8) (2 ) 5 Weight = (mass) (gravity) gravity on Earth is 9.8 mm/s/s. What is the weight of a 4.0 kg object? 13.8 N 14 . 0 ) (9. 8 ) = 3 2.45 N 39.2 N
