Q3 Car B is entering to the main highway at a curved road of p-100 m with a speed of 15 m/s while decreasing its speed at 2 m/s². Meanwhile, lorry C is traveling along the straight road with a speed of 30 m/s while decelarating at 3 m/s² as shown in Figure Q3. (b) (c) Calculate the velocity of car B relative to the lorry C, Vac. Calculate the acceleration of car B relative to the lorry C, Asc Calculate the direction angle of the velocity and acceleration, 0, 0,

An automobile goes down a hill that has a parabolic cross section as shown in the figure. Assuming that the horizontal component of the velocity vector has a constant magnitude v,, determine, a) the expression for the speed of the automobile in terms of x; b) the magnitude and direction of the acceleration.

Please do all parts.  Thank you!

A skier jumps off the ramp at point A and lands on the ground at point B. di d2 Values for the figure are given in the following table. Note the figure may not be to scale. TE Variable Value di 8 m d2 150 m 40 degrees a. Determine the initial magnitude of the velocity/speed of the skier, Vo. b. Determine the time of flight of the skier, t. 3.

hi Vo Vo V₁ = R - he A ball will be thrown from the initial position (pictured in green) to strike a target (pictured in red) while avoiding contact with the ceiling. The initial height is hi - 5 m, the ceiling is he - 25 m tall, and the target = = is ht = 20 m above the ground. The target is R = 40 ht m away, horizontally. Find the minimum initial speed V₁ that can achieve this m/s

A box is moving in the i direction with a constant acceleration. A mass, suspended from the top of the box by a linear spring (unstretched length of zero), is moving to the right as well and isn't moving with respect to the box (the spring isn't changing in length and θ is constant). The force exerted by the spring on the mass is given by its spring constant k times its extension. For the present case, the spring is extended 5 cm from its rest length, k = 30 N/m and m = 0.15 kg. What is the angle θ equal to, and what is the acceleration of the box? You can solve for this without using the computer
