Block A has a mass of 6kg and block B has a mass of 3kg. Block B is falling, as block B is falling it accelerates to the right at 1.32m/s^2, the coefficient of kinetic friction between block A and the surface is is 0.3. Assume the connecting rope has negligible mass. The pulley's mass is only to redirect the chord. a.) Find force exerted by the surface on block A

b.) Find the frictional force

c.) Find the tension in the chord

i don't know that i agree with that but what's the question ?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

1) estimating temperature to the nearest tenth of a degree

2) estimating the mass of the sample to the nearest tenth of a gram

4) the position of the cups of sand and water under the heat lamp
