Which of the following is true about * the object as it moves down? O The acceleration increases O The speed stays the same O The speed decreases O The speed increasesA car travels a distance of 150 km in 2 hours. What is the car's average speed?* 48 km/5 O 48 km/hr O Option 1 75 km/hr Two balls are thrown vertically upward, one with an initial speed twice that of * the other. The ball with greater initial speed will reach a height 12 that of the other O 8 times that of the other O twice that of the other 4 times that of the other A juggler throws a bowling pin straight up in the air. After the pin leaves his * hand and while it is in the air, which statement is true? The velocity of the pin is opposite its acceleration on the way up The velocity of the pin is never in the same direction as its acceleration O The velocity of the pin is always in the same direction as its acceleration, O The acceleration of the pin is zero
