Force on object at angle to acceleration

AI Thread Summary
To determine the force Joe must apply to the lawn spreader, first calculate the required acceleration using the final velocity of 1.35 m/s and the time of 1.3 seconds. Once the acceleration is established, analyze the forces acting on the spreader, ensuring the net force aligns with the direction of acceleration. The fundamental equation to apply is F=ma, where F is the net force, m is the mass of the spreader (10.5 kg), and a is the calculated acceleration. The angle of the handle (42°) may also affect the force component calculations. Completing these steps will yield the necessary force in Newtons.

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

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
