So I need help checking my answers on "Factors that Affect Kinetic Energy Quick Check".

Question

1. A student drops a basketball into a pool from a height of 5 meters while a friend records the approximate splash height. They want to make a bigger splash in their next trial. How can they achieve this?
A. They can use a ball that has a larger circumference
B. They can drop the same ball with less speed
C. They can use a ball with more mass ⬅️
D. They can drop the same ball from a lower height

2. Which characteristic will be affected by increasing the speed of an object from 30 mph to 40 mph?
A. weight
B. mass
C. gravitational attraction
D. kinetic energy ⬅️

4. A student drops a 350-gram rock and a 500-gram rock into a pool from a height of 8 meters. Which statement about the investigation is accurate?
A. The 500-gram rock causes a smaller splash because it has more mass
B. The 350-gram rock causes a larger splash because it has less mass
C. The 350-gram rock causes a smaller splash because it has more kinetic energy
D. The 500-gram rock causes a larger splash because it has more kinetic energy ⬅️
I skipped 3 and 5 because they both have pictures. Help!

Answer 1

Ok I got 4/5 but I got the answers so nvm

Answer 2

Wait but now I need the answers

Answer 3

The answers are shown in the first thing. But here to make it easy.
1) The ball with more mass
2) Kinetic energy
3) Changing the height affect mass
4) 500 g one because it has more kinetic energy
5) object X
Get one wrong commonly so teachers don't think your cheating

Answer 4

I got a 4/5 because of hidden here are REAL ANSWERS. You can trust me in I am in honors

1. b
2. b
3. a
4. c
5. a

Answer 5

Hidden was right except 3

3’s answer is : does changing the speed of an object affect its kinetic energy
