An archer must exert a force of 390 N on the bowstring shown in Figure (a) such that the string makes an angle of 0 = 38.0° with the vertical. k 어 a Need Help? (a) Determine the tension in the bowstring. N e (b) If the applied force is replaced by a stretched spring as in Figure (b) and the spring is stretched 25.0 cm from its unstretched length, what is the spring constant? N/m Read It b Watch It
At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with an amplitude of 20.0 cm. It is observed that the maximum speed of the bunch of bananas is 41.0 cm/s. What is the weight of the bananas in newtons? 85.97 X Assume conservation of mechanical energy to find the mass, and therefore the weight, of the bananas. N Need Help? Read It Master It
