Answer:
negative acceleration of 4m/s²
Explanation:
Given parameters:
Initial velocity = 66m/s
Final velocity = 26m/s
Time taken = 10s
Unknown:
Description of the acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time.
It is mathematically expressed as;
acceleration = 
v is the final velocity
u is the initial velocity
t is the time taken
Now insert the parameters and solve;
Acceleration = 
= -4m/s²
So, we see a negative acceleration of 4m/s²
Kinetic energy = 1/2mv2
= 1/2 x 2 x 3^2
= 9J
Answer:
The answer would be B
Explanation:
The atmosphere of Venus traps in lots of what from the Sun, it is the hottest planet in our solar system because of this. CO2 is a greenhouse gas and traps in heat. So B would be your answer.
Answer:
When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.
