A block of mass m = 8.40 kg, moving on a horizontal frictionless surface with a speed 4.20 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 8.40 block recoils with a speed of 0.400 m/s. In the figure, the blocks are in contact for 0.200 s. The magnitude of the average force on the 8.40-kg block, while the two blocks are in contact, is closest to Vi vf V M M Before After

The picture shows the wingspan for a cardinal and for an Andean condor. What formula explains why the cardinal beats the wings faster than the condor? 300 cm | 30 cm Cardinal Andean condor O A. 1 = mr? O B. W = 0/t OC.I= Frsine O D. T= I-a

Help, I think the answer is the 5th choice, but I am not sure.

Help me

I've attached a screenshot of the question i'm trying to solve and I have pictures of my work here https://imgur.com/a/bQ5IaC1 . My work for this problem is under the 2.44 title, any variable with an "s" in the subscript applies to the speeder, and any variable with a "c" in the subscript applies to the police car.

1. A pilot flies in a straight path for 1 h 30 min. She then makes a course correction, heading 10 degrees to the right of her original course, and flies 2 h in the new direction. If she maintains a constant speed of 610 mi/h, how far is she from her starting position?Your answer is    mi;Enter your answer rounded to two decimal places.   2. A steep mountain is inclined 74 degree to the horizontal and rises to a height of 3400 ft above the surrounding plain. A cable car is to be installed running to the top of the mountain from a point 880 ft out in the plain from the base of the mountain. Find the shortest length of cable needed.Your answer is    ft

1.37 (a) Write each vector in Fig. E1.37 in terms of the unit vectors î and ĵ. (b) Use unit vec- tors to express vector C, where C = 3.00A - 4.00B. (c) Find the magnitude and direction of C.

Please answer the attached question. Thanks.

Hello, can you please review my work and help me to do graphs for the problems and also I need “d” problem, I can’t deal with it. Thanks for your help!
