Question A 4 kg block resting on a flat, frictionless surface is attached to a spring with a spring constant of 460 N/m. A 60 g bullet is fired horizontally with a speed of 150 m/s and is embedded in the block. How far will the spring be compressed before the block and bullet momentarily […]
Question A powerful slingshot has an elastic band that is pulled back until a maximum spring force of Fma x is encountered (maximum force the person can exert). A projectile of mass M is released from rest. Which of the following strategies could be applied to ensure the max projectile speed leaving the slingshot? Assume […]
Question A particle of mass 5 kg is acted on by two forces, F1=(3i +4j) N and F2= (-2i +1j) N and is moved ri=(1i +1j)m to rf= (5i -4j)m. what is the net force on particle. I kept getting -9 when the real answer is -21 and I do not know what I am […]
Question Two blocks m1and m2 sit on a horizontal frictionless surface and are in contact with one another. A force F is applied to the box on the left (m1). The force that m2 exerts on m1 is known to be F12 .What is the applied force F in terms of m1, m2, and F12? […]
