A 1.0kg ball initially at rest rolls down a plane at 35 degrees. Find the net force.
pls i really need help
To find the net force acting on an object, you need to consider two types of forces: gravitational force and frictional force.
1. Gravitational Force (Weight):
The gravitational force acting on an object can be calculated using the formula: F_gravity = m * g, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.8 m/s^2). In this case, the mass of the ball is given as 1.0 kg, so the gravitational force can be calculated as F_gravity = 1.0 kg * 9.8 m/s^2.
2. Frictional Force:
The frictional force depends on the nature of the surface the ball is rolling on. In this case, it is not mentioned whether there is any friction acting on the ball. If there is no mention of friction, we assume it to be negligible or non-existent.
Therefore, the net force acting on the ball is simply the gravitational force, F_gravity.
Putting all the values together, the net force can be calculated as:
Net Force = F_gravity = 1.0 kg * 9.8 m/s^2.
Now, you can multiply the mass of the ball (1.0 kg) by the acceleration due to gravity (9.8 m/s^2) to get the net force acting on the ball.
