Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
A lower, easier gear, with the smaller chain ring up front and a largercog in the back, lets you accelerate faster.
The Main reason Dorothy might use a succes strategy is so that she can succed
Answer:
0.33m/s²
Explanation:
Given parameters:
Initial velocity = 19.9m/s
Final velocity = 4.4m/s
Time = 47.6s
Unknown:
Acceleration = ?
Solution:
To solve this problem, we use the expression below:
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Acceleration =
Acceleration = -0.33m/s²
This is a deceleration
Answer:
108.33 grams.
Explanation:
Given that,
Mass of a egg, m = 65 g
Volume of an egg, V = 60 cc
We need to find the mass of the salt dissolved in 100cc of water so that egg just float in water.
The density will remains constant,
So, the required mass is 108.33 grams.
