Given two displacement A=( 8i+4j-2k)m & B = (4i - 6j + 8k)m gind th magnitufe of the displacement 3A-B
A spring has a spring constant of 150 N/m and mass of 100 g is attached to it. The spring sits on horizontal frictionless surface and other end of the spring is attached to a solid block. The mass is pulled by 10 cm to stretch the spring and then let go. What will the highest velocity of the mass?
