While entering a freeway, a car accelerates from rest at a rate of 2.40 m/s2 for 12.0 s. (a) draw a sketch of the situation. (b) list the knowns in this problem. (c) how far does the car travel in those 12.0 s? to solve this part, first identify the unknown, then indicate how you chose the appropriate equation to solve for it. after choosing the equation, show your steps in solving for the unknown, check your units, and discuss whether the answer is reasonable. (d) what is the car’s final velocity? solve for this unknown in the same manner as in (c), showing all steps explicitly

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?

As seen in a us weather map, the h (or high) and l (or low) symbols indicate regions where surface air pressures are high or low, respectively, compared to surrounding areas. an h is plotted where the air pressure is highest and an l is plotted where the air pressure is lowest. proceeding outward and away from the center of a high pressure system, the air pressure "
