4, Write an equation that relates Vnw Vm, ,and V\": (the velocrty ofjet airliner relative to Earth). 5. What are the speed and direction ofthe aircraft relative to the Earth? 20) A curve has a radius of 25m and a banking angle of theta=45 degree. Assuming a static coefcient of friction muis=0.3 of the car's tires to the road. a. Draw a free body diagram of the car on the bank. b. what is the speed you can safely use for the car to not slide up or down the embankment? c. What would happen if the car's speed was lower than you answer from (b)? d. What would happen if the car's speed was higher than you answer from (h)? 9. Assuming there is no friction between the car's tires and the road. Could the car still get around the curve? If so. what is the precise speed required? If not, explain. 21) Two objects with mass m1 =5 kg and m2=3 kg are connected by a light string passing over a light. frictionless pulley. The 5 kg block is released from rest at a point h=4 m above the table. 3. Determine the speed of each block when the two pass each other. b. Determine the speed of each block at the moment the 5 kg block hits the table, c. How much higher does the 3 kg block travel after the 5 kg block hits the table? "ill A 14 \"I 2 v 22) A 65kg person throws a 0.045 kg snowball forward With a ground speed of 30.0 m/s, A second person, with a mass of 60.0 kg, catches the snowball. Both people are on skates. The first person is initially movmg forward with a speed of 2.50 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard friction between the skates and the ice. 23)According to the figure, we have two block of mass m, = 1 kg, and in2 = 1.5 kg that are connected to each other through a pulley with negligible friction with the radius of R = 10 cm. The system is released from rest and block 2 falls 1 meter in 2 seconds without the cord slipping on the pulley. 1. What is the magnitude 0' the acce eration 0' the g ocls
