A force of 2.0 n exerted on an object for 0.1 seconds increases the objects velocity by 1.0 m/s you what is the mass of the object?

The mass of the object is 0.2 kg

Explanation:

The magnitude of the applied force = 2.0 N

The duration of application of the force = 0.1 second

The increase in velocity given to the body by the force = 1.0 m/s

From the equation of motion under acceleration, we have;

v = u + a·t

Therefore;

a = (v - u)/t

Where;

v = The final velocity

u = The initial velocity

t = The time taken for the change in velocity = 0.1 s

Given that the change in velocity = 1 m/s, we have;

v - u = 1 m/s

∴ a = (v - u)/t = 1 m/s/(0.1 s) = 10 m/s²

The acceleration, a = 10 m/s²

The equation for the applied force, F is F = Mass, m × Acceleration, a

Therefore, when the applied force, F = 2.0 N, and the acceleration, a is a = 10 m/s², we have;

F = Mass, m × Acceleration, a

2.0 N = Mass of the object × 10 m/s²

∴ Mass of the object = 2.0 N/10 m/s² = 0.2 kg

The mass of the object = 0.2 kg.

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.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
