Answer:
<h3>The answer is 2 m/s²</h3>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
where
f is the force
m is the mass
From the question
f = 20 N
m = 10 kg
We have
We have the final answer as
<h3>2 m/s²</h3>Hope this helps you
Answer:
The tension in the cord is
Explanation:
Given:
M = mass
b = radius
R = spool of radius
The equation is:
(eq. 1)
The sum of forces in y:
∑Fy = Mg - T = Ma
Replacing in eq. 1
Answer:
Explanation:
It is given that,
Speed of the projectile is 0.5 v. Let h is the height above the ground. Using the first equation of motion to find it.
Initial speed of the projectile is v and final speed is 0.5 v.
g is the acceleration due to gravity
Let h is the height above the ground. Using the second equation of motion as :
So, the height of the projectile above the ground is . Hence, this is the required solution.
