- 7. How much force is needed to pull a spring with a spring constant of 16 N/m a distance of 30 cm?6. While demonstrating springs, i pushed on the top of my ball point pen with a maximum force of 0.901 newtons which compressed the little springs in the pen by 0.0132. then i help the pen top next to a gold ball and released the spring. it pushed the ball which rolled across the table. the mass of the ball was 0.0379 kg. calculate the speed of the golf ball after the pen pushed it6. The static coefficient of friction μs applies to an object of mass m placed on a platter that revolves about a vertical axis at frequency f. Derive an expression for the maximum distance r from the center of the platter at which the object can remain without sliding off the platter.
- 3. Two balls with masses of 1.80 kg and 5.50 kg travel toward each other at speeds of 10.0 m/s and 3.90 m/s, respectively. If the balls have a head-on inelastic collision and the 1.80-kilogram ball recoils with a speed of 7.80 m/s, how much kinetic energy is 19 shpl19 lost in the collision? shp shpll 119 19 shpi19Please help! Thank you! Q1) Required info: marble column with a cross-sectional area of 26.1 cm^2 supports a load of 7.0 x10^4 N. The marble has a Young's modulus of 60 GPa and a compressive strenath of 200 MPa. a) What is the stress in the column? b) What is the strain in the column? c) If the column is 2.00 m high, how much is its length changed by supporting the load? d) What is the maximum weight the column can support?Fm 3.4 cm 30 cm mg 2. Determine how much force is exerted by the bicep muscle in order to hold up a mass of 15 kg. The muscle pulls 10 degrees from the vertical.
- 4. Under certain conditions, wind blowing past a rectangular speed limit sign can cause the sign to oscillate with a frequency w (see Fig.). Assume that w is a function of the sign width, b; sign height, h; wind velocity, V; air density, p; and an elastic constant, k, for the supporting pole. The constant, k, has dimensions of Nm. (a) Develop a suitable set of pi terms for this problem using b, V, and p as repeating variables. (b) List all the other possible combinations of repeating variables that could have been utilized for this problem. SPEED LIMIT 40Hummingbirds may seem fragile, but their wings are capable of sustaining very large forces and accelerations. as showndata for the vertical position of the wing tip of a rufous hummingbird. What is the maximum acceleration of the wing tips, in m/s2 and in units of g?
