Matching Numerical 2: In the figure, block 1 of mass $m_1$ slides from rest along a frictionless ramp from height $h = 3.3 m$ and then collides elastically with stationary block 2, which has mass $m_2 = 5m_1$. After the collision, block 2 slides into a region where the coefficient of kinetic friction $\mu_k = 0.10$ and comes to a stop in distance $d$ within that region. Match the quantity on the left with the correct value in SI units on the right. Each value on the right is used only once. 21) speed of block 1 just before the collision A) 3.7 22) speed of block 2 just after the collision B) 1.5 23) speed of block 1 just after the collision C) 8.0 24) $d$ 25) maximum vertical height up the ramp block 1 reaches after the collision D) 5.4 E) 2.7

Sodium ions enter the postsynaptic cell, resulting in a slight depolarization of that neuron. Calcium ions enter the cell, resulting in a slight depolarization of the postsynaptic neuron. The glutamate released from the axon terminal binds to both AMPA and NMDA receptors but only activates the NMDA receptors. The AMPA receptors depolarize the postsynaptic neuron and drive the Mg$^{2+}$ plug out of the NMDA channel.
The answers should be in the following ranges: a) P = 1331.5 lbf b) 1000 lbf < Pallow < 1500 lbf 1. Just because you were bored and found these metal parts, you've built this assembly and decided to run some tests on it. Thanks to the serial numbers on them, you've determined that the parts you found are a brass cylinder with modulus of elasticity E = 15 x 10^6 psi and diameter d1 = 0.25 in. and a steel pipe Es = 30 x 10^6 psi with inner diameter d = 0.28 in. and outer diameter d3 = 0.35 in. You've cut them both down to a length of 4.0 in. Steel shell Brass core a) If load P shortens the length of the assembly by 0.003 in, what is the magnitude of P? Round to 2 decimals. kips b) The steel and brass have allowable stresses 22 ksi and 16 ksi respectively. What is the maximum permissible load Pmax? (Hint: use equations from example 2-8) Round to 2 decimals. kips
