Force on object at angle to acceleration

In summary, the conversation discusses a problem involving a lawn spreader and the force needed to accelerate it. It mentions the weight of the spreader, the angle of the handle, and the desired acceleration and time. The homework equations are not specified, but it is suggested to use F=ma to find the required force. The conversation ends with a question about the solution to the problem.

Homework Statement



Joe pushes down the length of the handle of a
10.5 kg lawn spreader. The handle makes an
angle of 42◦ with the horizontal. Joe wishes to
accelerate the spreader from rest to 1.35 m/s
in 1.3 s.
What force must Joe apply to the handle?
Answer in units of N.

Homework Equations


I can't even figure out which equation to use :(

Can you figure out what the acceleration should be based on what is given?

If you can, then you can analzye all the Forces on the spreader and make sure that the net force is in the same direction as the acceleration. Then it just comes down to F=ma

I can find acceleration, but not sure how else to finish it

Related to Force on object at angle to acceleration

What is the formula for calculating the force on an object at an angle to acceleration?

The formula for calculating the force on an object at an angle to acceleration is F = m * a * cos(theta), where F is the force, m is the mass of the object, a is the acceleration, and theta is the angle between the force and acceleration vectors.

How is the direction of the force on an object at an angle to acceleration determined?

The direction of the force on an object at an angle to acceleration is determined by the angle between the force and acceleration vectors. This can be calculated using the dot product formula: F * cos(theta), where F is the magnitude of the force vector and theta is the angle between the vectors.

What is the relationship between the force, mass, and acceleration of an object at an angle?

The relationship between the force, mass, and acceleration of an object at an angle is described by Newton's Second Law of Motion: F = m * a. This means that the force on an object is directly proportional to its mass and acceleration. In the case of an object at an angle, the force can be calculated using the formula F = m * a * cos(theta).

How does the force on an object change when the angle between the force and acceleration vectors is altered?

The force on an object changes when the angle between the force and acceleration vectors is altered. This is because the magnitude of the force vector is affected by the angle between the vectors. As the angle decreases, the force increases, and vice versa. However, the direction of the force remains the same.

Can the force on an object at an angle to acceleration ever be greater than the force of gravity?

Yes, the force on an object at an angle to acceleration can be greater than the force of gravity. This can happen when the angle between the force and acceleration vectors is less than 90 degrees. In this case, the force vector is acting in the same direction as the acceleration vector, resulting in a net force that is greater than the force of gravity.
