Answer: acceleration is 0.5 m/s^2
Explanation: From the question, we are given the following parameters
Time t = 20s
Initial velocity U = 0
Final velocity V = 10 m/s
Using first equation of motion,
V = U + at
Where a = acceleration
Substitute all the parameters into the formula to get acceleration a
10 = 0 + 20a
10 = 20a
Make a the subject of formula
a = 10/20 = 0.5 m/s^2
The acceleration is 0.5 m/s^2
Answer:
the training of the body to improve its function and enhance its fitness. ... The distinguishing characteristic of exercise is that it is a structured activity specifically planned to develop and maintain physical fitness.
Exercise improves brain function.
Exercise delivers oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.
Answer:
The speed of the cart and clay after the collision is 50 cm/s .
Explanation:
Given :
Mass of lump , m = 500 g = 0.5 kg .
Velocity of lump , v = 30 cm/s .
Mass of cart , M = 1 kg .
Velocity of cart , V = 60 cm/s .
We know by conservation of momentum :
Here , is the speed of the cart and clay after the collision .
Putting all value in above equation .
We get :
Hence , this is the required solution .
Answer:
Velocity
Explanation:
"The principle is that the slope of the line on a position-time graph is equal to the velocity of the object. If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s."
