- An adventurous archeologist (m = 5 85.0 kg) tries to cross a river by swinging from a vine. The vine is 10.0 m long, and his speed at the bottom of the swing is 8.00 m/s. The archeologist doesn’t know that the vine has a breaking strength of 1 000 N. Does he make it across the river without falling in?A heavy ball with a weight of 150 N (m = 15.3 kg) is hung from the ceiling of a lecture hall on a 4.6-m-long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.6 m/s as it passes through the lowest point. What is the tension in the rope at that point?G=25
- Dana loads luggage into an airplane using a conveyor belt tilted at an angle of 20°. She places a few pieces of luggage on the belt before it starts to move, then she turns the belt on. It takes the belt 0.70 s to reach its top speed of 1.2 m/s. Does the luggage slip? Assume μs = 0.50 between the luggage and the belt.The figure shows a container of mass m1 = 3.4 kg connected to a block of mass m2 by a cord looped around a frictionless pulley. The cord and pulley have negligible mass. When the container is released from rest, it accelerates at 1.9 m/s² across the horizontal frictionless surface. What are (a) the tension in the cord and (b) mass m2?An adventurous archeologist (m = 85.5 kg) tries to cross a river by swinging from a vine. The vine is 11.0 m long, and his speed at the bottom of the swing is 7.50 m/s. The archeologist doesn't know that the vine has a breaking strength of 1,000 N. Does he make it safely across the river without falling in? Yes No
- An object with a mass of 1.53 kg is initially at rest upon a horizontal, frictionless surface. An applied force of 4.94 N i acts on the object for 2.2 s. What is the object's final speed?An constant applied force of 40.1 N lifts an 2.50 kg mass straight up, resulting in a final speed of 3.6 m/s. What distance did the mass move if it was initially at rest?A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance. The student hits the elevator button and it begins to move upwards. While the elevator is moving, the student records this information Time = 0 to 3.0 sec the balance reads 278 grams Time = 3.0 - 12 sec the balance reads 240. grams Time = 12.0 to 15.0 sec the balance reads 192 gram How far up (in meters) did the elevator travel? Consider: UP to be (+), DOWN to be (-) and g =9.8 m/s2 . ROUND YOUR ANSWER TO A WHOLE NUMBER of meters (no decimal places) HINT: This problem requires finding THREE different displacements and adding them up! 2nd HINT: You will need to (A) use your equations of motion or (B) make a v-t graph to find those displacements!
