The magnitude of the vectors F is 20 N, the force on the right is applied at an angle 55◦ and the the mass of the block is 75 kg.
If the surface is frictionless, what is the magnitude of the resulting acceleration?
Answer in units of m/s2.
Well, you've given me a bit of a mathematical mouthful there! It sounds like you're dealing with some physics calculations, which can be a real pain in the funny bone.
But fear not, for Clown Bot is here to lighten the mood!
Now, let me juggle some numbers for you. We have a magnitude of 20 N and an angle of 55 degrees, along with a mass of 75 kg. But wait, the surface is frictionless, so we won't be needing any slippery banana peels for this one!
I'm gonna let you in on a little secret: the magnitude of the resulting acceleration can be found using good ol' Newton's second law: F = ma, where F is the net force and m is the mass.
In this case, the net force is given by the magnitude of the vector, which is 20 N. So we can rewrite our equation as 20 N = 75 kg * a. Now, we just need to solve for a!
Dividing both sides of the equation by 75 kg, we get a = 20 N / 75 kg. Crunching the numbers, we find that a ≈ 0.267 m/s².
That's the magnitude of the resulting acceleration! So, the answer you're looking for is approximately 0.267 m/s². But hey, don't forget to thank Clown Bot for the giggle-filled calculation!
To find the magnitude of the resulting acceleration, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
First, we need to determine the horizontal component of the applied force. Given that the force is applied at an angle of 55°, we can use trigonometry to find the horizontal component.
Horizontal component of the force, Fx = F * cos(angle)
= 20 N * cos(55°)
≈ 10.18 N
The net force acting on the object in the horizontal direction is equal to the horizontal component of the applied force since there is no friction.
Net force, Fnet = Fx
= 10.18 N
Now, we can calculate the magnitude of the resulting acceleration using Newton's second law.
Acceleration, a = Fnet / m
Given:
Fnet = 10.18 N
m = 75 kg
Substituting these values into the equation, we get:
Acceleration, a = 10.18 N / 75 kg
≈ 0.14 m/s²
Therefore, the magnitude of the resulting acceleration is approximately 0.14 m/s².
Calculate the net force in the direction of motion. I need to see your figure to do that. It may be 20 cos 55 newtons
Divide that net force by the mass to get the acceleration.
