A rudimentary elevator is constructed by connected an elevator car of mass Me = 568 kg to a large counterweight of mass Me = 730 kg. A man of mass m = 90 kg steps on the elevator car and then the counterweight is released. a) Draw the free body diagrams for the elevator car, the counterweight, and the man. b) What is the acceleration of the counterweight (magnitude and direction)? c) What is the tension in the string? d)...
Please help me solve questions 6 6) A 50 kg person on a scale is in an elevator. The elevator is at rest for 3 seconds. Then it takes 0.8 seconds to accelerate to 6 m/s moving down. It moves elevator then takes 1.2 seconds to slow to a stop. at this speed for 5 seconds. The 6a) Draw an FBD of the situation during both of the accelerations. 42 What is the acceleration of the person during the first...
I need hep figuring out these three problems Force 3 Total 10 3. In the system shown in Figure, a horizontal force Fx-30N acts on an object of mass m,=10kg. The horizontal surface is frictionless. m, 3kg, (a) Find and draw all the forces using free body diagram for each boxes. (b) build equations for both using Newton's 2nd law for both objects. (c) solve the equations to find the acceleration of both objects. (d) solve the equations to find...
Name: A speeder travelling at 40 m/s along a straight road sees a police car in the distance. He applies the brakes and the car decelerates at a constant rate of5 m/s (3 pts) (3 pts) a) How long does it take for the car to reach 25 m/s? b) How far does the car travel during this time? 2. Study the following graph and answer the questions below 1Agraph of position vs. time TE (3 pts) (3 pts) (3...
1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...

A right triangle has hypotenuse 13 cm and one side 7 cm. Find the length of the other side, and the sine, cosine and tangent of each of the other two angles. A man running 4 m/s is passed by a car at 20 m/s, both heading East. What is the velocity of the man relative to the car? How far apart are the 20 seconds after the car passes the man? A ball is thrown vertically upwards from the...
