Ok, so m1 = 5,000 kg moving 40 m/s to the right and m2 = 3,000 Kg and moving 40 m/s to the left.
a. How fast are the two masses moving after the collision? Pay no attention to the
15 mph after picture.
b. If the brakes lock and the coefficient of friction is 0.4, how far will the truck-car.
slide?
c. Explain the change in momentum of the truck and the car relative to each other
(i. e. the truck experienced a greater change in momentum than the car because
...). Hint: there are only three choices, the truck experiences a greater change in
momentum, the car experiences a greater change in momentum or the car and
truck experience the same change in momentum.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
