lots of questions
1) a 2N and 6N force pull on an object to the right and a 4N force pulls to the left a 0.5 kg object what is the net force on the object
2)a 20mkg bike accelerates at 10m/s2 with what force was the person pedaling
3)if a person is pushing a cart with a force of 40 newtons and it accelerates at 0.5 m/s2 what is the mass of the cart
4)what is the acceleration of a 3 kg rock that is thrown with a force of 18N
if a person is pushing a cart with a force of 40 newtons and it accelerates at 0.5m/s2, what is the mass of the cart?
A 2 N and 6 N force pull on an object to the right and a 4 N force pulls to the left a 0.5 kg object. What is the net force on the object?
6-2=4 just subtract the answer because it’s says “what is the”
1) To find the net force on an object, you need to calculate the sum of all the forces acting on it. In this case, you have a 2N force and a 6N force pulling to the right, and a 4N force pulling to the left. Since the force pulling to the left is opposing the forces pulling to the right, you subtract it from the sum of the forces pulling to the right.
Net force = (2N + 6N) - 4N = 8N
Therefore, the net force on the object is 8N to the right.
2) To find the force exerted by a person when pedaling a bike, you can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = ma).
Force = mass × acceleration
In this case, you're given the acceleration of the bike (10 m/s²) and the mass of the bike (20 mkg, which is equivalent to 0.02 kg). Substitute those values into the equation:
Force = (0.02 kg) × (10 m/s²) = 0.2 N
Therefore, the person exerted a force of 0.2 Newtons while pedaling the bike.
3) To find the mass of the cart, you can rearrange Newton's second law of motion equation (F = ma) to solve for mass.
Mass = Force / Acceleration
Given that the pushing force is 40 N and the acceleration is 0.5 m/s²:
Mass = 40 N / 0.5 m/s² = 80 kg
Therefore, the mass of the cart is 80 kilograms.
4) To find the acceleration of the rock, you can rearrange Newton's second law of motion equation (F = ma) to solve for acceleration.
Acceleration = Force / Mass
Given that the force acting on the rock is 18 N and the mass is 3 kg:
Acceleration = 18 N / 3 kg = 6 m/s²
Therefore, the acceleration of the rock is 6 m/s².
These are not difficult questions. You are going to have to make an effort if you expect to learn physics.
I or someone will be around to critique your thinking.
