A1300 kg car and a 2600 kg pickup truck approach highway that has a radius of a curve on a 249 m a) draw the free body diagram b) express all required equations c) at what angle should the highway engineer bank this curve so that vehicles traveling at 66.0 mi/h can safely round it regardless of the condition of their tires? d) should the heavy truck go slower than the lighter car? e) as the car and truck round the curve at 66.0 mi/h, find the reaction force of the road on each one due to the highway surface

What do you think car designers do if the damage caused by a crash test is too severe?

If the radius of curvature of the cornea is 0.75 cm when the eye is focusing on an object 36.0 cm from the cornea vertex and the indexes of refraction are as described before, what is the distance from the cornea vertex to the retina? express your answer to two significant

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.
