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

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...

anyone?

So I am assuming you mean: 7m/9.8=.7142857s to make it to the bottom =t using d=(Vi+Vf/2)(t) therefore 9m=(0+Vf/2)(.7142857s) Vf=25.2 that not right?

Could you help me out a little more?

I haven't been able to

Homework Statement You are standing at the top of a cliff that has a stair step configuration. There is a vertical drop of 7 m at your feet, then a horizontal shelf of 9 m, then another drop of 3 m to the bottom of the canyon, which has a horizontal floor. You kick a 0.26 kg rock, giving it an...

Homework Statement A man pushes a mop across the floor causes the mop to undergo two displacements. The first has a magnitude of 235cm and makes an angle of 131⁰ with the positive x-axis. The resultant displacement has a magnitude of 215cm and is directed at an angle of 49⁰ to the positive...
