A carnival ride consists of a car travelling in the horizontal plane connected to a rigid rod with a length of 3 m and rotating around a fixed point O as shown in the image below. The car's engine provides a time-varying force perpendicular to the rod given by F(t) = 30t² + 120 N. The total mass of the car is 120 kg. The car is initially moving at 1 m/s. Calculate the car's speed after the force is applied for 3 s. The coefficient of kinetic friction between the car and the ground is 0.1.

You are the technical consultant for an action-adventure film in which a stunt calls for the hero to drop off a 19-m-tall building and land on the ground safely at a final vertical speed of 5 m/s. At the edge of the building's roof, there is a 100-kg drum that is wound with a sufficiently long rope (of negligible mass), has a radius of 0.4 m, and is free to rotate about its cylindrical axis with a moment of inertia I0. The script calls for the 76-kg stuntman to tie the rope around his waist and walk off the roof. (a) Determine an expression for the stuntman's linear acceleration in terms of his mass m, the drum's radius r, and moment of inertia I0. (b) Determine the required value of the stuntman's acceleration if he is to land safely at a speed of 5 m/s.
Consider the Atwood machine, where two masses m1 = 12.6 kg and m2 = 4.2 kg are connected by an ideal wire that passes through a pulley of mass M = E of radius R = 0.15 m. The pulley is attached, but can rotate freely around its axis of symmetry. As shown in the Figure below, at the initial instant the mass m1 is at a height h= 3.29 m in relation to m2. Knowing that the system starts from rest, and that the magnitude of the linear velocity of m1 when the masses pass through the same vertical position is v=3.31 m/s, what is the mass M of the pulley? Here, assume the acceleration due to gravity as g=10 m/s², the pulley moment of inertia as I=MR2 and, finally, that the wire does not slide on the pulley. Choose one: a. 4,2 kg b. 14,7 kg c. 10,5 kg d. 6,3 kg e. 12,6 kg f. 16,8 kg g. 8,4 kg h. None of the other alternatives.

What minimum coefcient of friction µs is needed to satisfythe conditions of the problem?
A space of mass 120 kg is going to use a planet for a gravitational assist- that is, use the planet's gravity to change its direction of travel without expending any fuel. It is initially moving at a velocity of 280 m/s and at an angle of theta initial = 53 degrees, at a distance of 11500 km from the center of the planet. Given an expression for the angular momentum of the spacecraft using the coordinate system specified in terms of m, r0, v0, theta initial, and vector units i, j, k If the spaceship whips around the planet to the other side so that the angle is theta 35 and is moving at 95 m/s, how far, in kilometers, from the planet is it?
a solid brass ball of mass 0.280 g will roll smoothly along a loop-the-loop track when released from rest along the straight section. The circular loop has radius R = 14.0 cm, and the ball has radius r < R. (a) What is h if the ball is on the verge of leaving the track when it reaches the top of the loop? If the ball is released at height h = 6.00R, what are the (b) magnitude and (c) direction of the horizontal force component acting on the ball at point Q?
The two balls are attached to the light rigid rod, which is suspended by a cord from the support above it. If the balls and rod, initially at rest, are struck with the force F = 11.5 lb, calculate the magnitudes of the corresponding acceleration of the mass center and the rate at which the angular velocity of the bar is changing.

In the assembly below the system can rotate around the vertical axis. The left part is a square where R = 0.1 meters, and the mass of each of the four thin bars is uniform and is 0.1 kg. On the left is a massive sphere of radius R = 0.2 meters and Mass M = 0.3 kg. Assume that the system rotates with constant period T = 2.0 s, when, without any external action, as three leftmost bars detach from the system, leaving only the right vertical bar (on the axis) and sphere . What will be the new period of system revolution? Note: Note that in this case there is no difference between angular velocity and frequency.
