Aparticle moves along a circular path over a horizontal xy coordinate system, at constant speed. at time t1 = 4.50 s, it is at point (5.80 m, 5.60 m) with velocity (3.50 m/s) j and acceleration in the positive x direction. at time t2 = 11.7 s, it has velocity (–3.50 m/s) i and acceleration in the positive y direction. what are the (a) x and (b) y coordinates of the center of the circular path? assume at both times that the particle is on the same orbit. expert answer

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

answer; how far out of place which the object finished relative to the starting location;

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.
