A bolck of mass 5 kg lies on rough horizontal surface .Whena horizontal force of 24.5 N is applied to the block , at just starts sliding while 19.6N is enough to keep it sliding at uniform velocity find i) coefficient of static friction
ii)coefficient of kinetic energy
Find also the acceleration of the block when at rest is acted by a force of 24 N and a negligible impulse is imparted.​

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

answer: 31, 5556. 952 seconds

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
