Answer:
<h2>3.5 m/s²</h2>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
m is the mass
f is the force
From the question we have
We have the final answer as
<h3>3.5 m/s²</h3>Hope this helps you
Answer:
A) total intensity = 5x10^-4W/m2
B) total intensity = 5.34x10^-4W/m2
Explanation:
Detailed explanation and calculation is shown in the image below
Answer:
23.5 m/s
Explanation:
The velocity of the car in decelerated motion is given by
v = u + at
where
v = 0 is the final velocity
u is the initial velocity
a is the acceleration of the car
t = 3.0 s is the time it takes for the car to stop
The acceleration of the car is given by the frictional force, which is the only force acting on the car along the direction of motion, so:
where
is the coefficient of friction
Solving the previous equation for u, we find the initial velocity:
