The athlete with a mass of 85 kg moves from point A with a velocity vA. The circular orbit it slides has a radius of 4.9 meters and an angle of 60 degrees. As it is know that the reaction force affecting the athlete at the D point is 4. (Coefficient of Dmg); a) Calculate the athlete initial velocity vA and the velocity vB at point B. b) Calculate the height y, which is the highest distance that the athlete can climb after point B, and the distance between BC that he can travel horizontally.
A worker develops a tension T in the cable as he attempts to move the 54-kg cart up the 18° incline. Determine the resulting acceleration a of the cart if (a) T = 142 N and (b) T = 208 N. Neglect all friction, except that at the worker's feet. The acceleration a is positive if up the slope, negative if down the slope. T 54 kg 11° m/s² 18° Answers: (a) T = 142 N, a = (b) T = 208 N, a = i i m/s²

The 65-kg crate is stationary when the force P is applied. Determine the resulting acceleration of the crate if (a) P = 0, (b) P = 223 N, and (c) P = 488 N. The acceleration is positive if up the slope, negative if down the slope. P Part 1 P 65 kg. Incorrect Part (o). We need to decide if the block moves. The easy way to make this decision is to assume that the block does not move and then to test this assumption. If P = 0, what friction force F is needed to keep the block from moving? 4₂ mg Answer: F = 1 260 [#₂ = 0.27 HA=0.20 N N

A rocket runs out of fuel in the position shown and continues in unpowered flight above the atmosphere. If its velocity in this position was 567 mi/hr, calculate the maximum additional altitude h acquired and the corresponding time t to reach it. The gravitational acceleration during this phase of its flight is 30.0 ft/sec². Vertical 22% Answers: h = i t = Mc v = 567 mi/hr mi sec
Block A with a mass of 20 kg moves at a constant speed of 2 m/sec, while Block B with a mass of 10 kg stops it multiplies. Block B was connected to two parallel plateaus with spring coefficients k1=500 N/M and k2=1000 N/m. A after hitting Block B Block, they move together (at the same speed) by compressing the spring. Ground with blocks if friction between the Springs is omitted, the maximum amount of compression (shortening) in the Springs is approximately what are they? 2 m/ SEC ww.
