Sorry to say but I know that t(e introduction is first and the coda is last
Hi,
The answer is letter D, speed. You can calculate potential energy as mass times height times gravitational acceleration.
Hope this helps!
Answer:
Independent variable: Force applied to the car
Dependent variable: The acceleration of the car
Explanation:
A scientific experiment involves three variables which are classified mainly as independent, dependent and constant variables.
The independent variable is the variable which can be changed or changes itself like weather, natural conditions and in a given question, the applied force on the car is considered.
The dependent variable is the variable which depends on the independent variable that is the force applied on the car. Therefore, the acceleration of the car can be considered as a dependent variable as it changes according to the applied force.
Answer:
Explanation:
1) either all the way to the ground, or, if the cliff is high enough,
h = ½(9.8)1.4² = 9.6 m
2) If the cliff is high enough and we ignore air resistance
v = 9.8(2.7) = 26 m/s
