A3000 kg hino truck moving at a speed of 40 ms^-1 suddenly applies brakes and the vehicle slides 40m before it comes to rest. the coefficient of kinetic friction between the surface of the road and the wheels is uk=0.05.
a) calculate the kinetic friction of the force.
b)calculate the acceleration of the truck.
c) calculate the force applied by the brakes.

terd muffin is the correct answer

its a 5.5 n

glad that

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.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
