Before throwing a 0.821 kg discus, an athlete rotates it along a circular path of radius 1.19 m. The maximum speed of the discus is 18.7 m/s. Determine the magnitude of its maximum radial acceleration. Answer in units of m/s2.

A 1.3 kg mass accelerates at 5.8 m/s2 in a direction 36◦ north of east. One of the two forces acting on the mass has a magnitude of 17.3 N and is directed north. Determine the magnitude of the second force. Answer in units of N.

A pulley is massless and frictionless. 3 kg, 2 kg (on the left), and 6 kg (on the right) masses are suspended What is the tension T1 in the string be- tween the two blocks on the left-hand side of the pulley? Can I solve this like if it was two masses? My...

A pulley is massless and frictionless. 3 kg, 2 kg, and 6 kg masses are suspended. What is the tension T1 in the string between the two blocks on the left-hand side of the pulley?

A 33.5 kg person stands on a 67 kg platform. He pulls on the rope that is attached to the platform via the frictionless lower-right pul- ley. He pulls the rope at an angle of 35◦ to the horizontal, as shown in the figure below. Assume: g = 9.8 m/s2 . Igno...

A force of 23.52 N pushes and pulls to blocks as shown in the figure below. The vertical contact surfaces between the two blocks are frictionless. The contact between the blocks and the horizontal surface has a coefficient of friction of 0.29. The acceler...

thank you so much!!!

How do I do that? the only info missing is the angle is 60 degrees... force > => block1 block2 / force @60deg uk=0.29

Hi, I am confused on the height change. By 4.9 did you mean 4.8? and if so do I set it equal to zero to solve? is the v in the centripetal force different from the v in KE?
