Even by doing that though, I don't see how I'd find a because like you said there would be 2 unknowns...

Homework Statement What is the acceleration of the masses as shown in the second attached image. m1 = 0.9kg, m2 = 1.6kg, and m3 = 2.4kg. (Assume the table is frictionless) Homework Equations \sumF=ma F_mg+FN = ma The Attempt at a Solution I figured everything up to the point...

Homework Statement T here are 2 blocks connected by a string, as shown in the first image attached. The smooth inclined surface makes an angle of 40 degrees with the horizontal, and the block on the incline has a mass m1 = 7.9kg. What is the mass of the hanging block m2 that will cause the...

thank you!

Homework Statement A car starting from rest moves with a constant acceleration of 1.8 m/s2 for 10 s, then travels with a constant speed for another 12 s, then finally slows to a stop with a constant deceleration of 1.9 m/s2. How far does it travel? Homework Equations The Attempt at...

Homework Statement A pitcher throws horizontally a fast ball at 135 km/h toward home plate, which is 18.3 m away. Neglecting air resistance (not a good idea if you are the batter), find how far the ball drops because of gravity by the time it reaches home plate. Homework Equations...

Homework Statement A ball thrown into the air lands on the same horizontal level, 38 m away, and 3 s later. Find the magnitude of the initial velocity. Homework Equations x = vox The Attempt at a Solution I just plugged the x distance which is 38m and the time which is 3s into...
