2 A block with a mass, m = as shown to the right . a. Calculate the magnitude of the normal force on the block. 15kg, is placed on an incline (0 = 16°) m b. Calculate the minimum coefficient of static friction so that the block will not slide down the ramp. c. Calculate the kinetic coefficient of friction if the block slides with an acceleration of 1.2m/s down the ramp.

1. Two masses m, and m, are connected by a string which passes over a massless, frictionless pulley. Mass m, > m,. When released from rest the acceleration of the system is: т+ m, а. д m- m 1 m,- m. 1 2 b. g m,+ m, m. С. д m,- m m,m, d. g т,-т, т, е. д m,+ m, 1

Which acceleration below would you feel the most? a. 5 m/s^2 b. 10 m/s^2 c. 15 m/s^2 d. 20 m/s^2

Q5 again please

Hi, please can you help with the second question, I was able to do the first

Q8. As shown in the image below, objects A and B connected by a rope with fixed length of 7 ft. For absolute dependent motion analysis, the datum line and the position variables for A and B, SA and SB, are also provided. Assume the rope never has any slack, determine the velocity of object B when the velocity of object A is VÀ = 4.4 ft/s at sà = 4.5 ft. In your answer, negative sign must be included if the motion of Bis opposite to the direction of its given position variable. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. B Answer: 3 ft A B SB 3 ft Datum A

block and the ramp is 0.26. It compresses the spring 5.3 cm before coming to a stop. How much was the distance d it travelled down the ramp before contacting the spring?

Please solve A-C or do not attempt! I couldnt solve this lecture problem in class. Please explain, Thank you.

Please asap
