Consider a=70 cm·kg and b=35 mg·km identify which operations are possible, and which are not. if the operation is possible, also check the given result. examples: you cannot add 5m and 3s, so "this operation is impossible." you can add 5m and 3cm, so "this operation is possible" - however, the answer 8m would false. you can divide a by b, and get 20 you can multiply a and b, and get 0.0245 m·kg you can add a and b2, and get 0.701225 m·kg you can multiply a and b, and get 0.0245 m2kg2 you can add a and b, and get 0.735 m·kg

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
