<span>The reaction force would be the exact opposite of the action. In this case, choice (c) would be the most correct. If the action is the ball pushing the glove, the reaction would then be the glove pushing back on the ball.</span>

A force of 150 N is continuously applied to an object with a mass of 11 kg over a distance of 2.5 m.The object slides over a sur
Ivahew [28]

Answer:

Final velocity will be 7.31 m/sec

Explanation:

We have given applied force F = 150 N

Mass of the object m = 11 KG

Distance traveled by the object s = 2.5 m

Coefficient of kinetic friction \mu _k=0.3

Acceleration due to gravity g=9.8m/sec^2

So frictional force applied on the object f=-\mu _kmg=-0.3\times 11\times 9.8=-32.34N

So net force = 150-32.34 = 117.66 N

As work done us equal to W=Fs

So work done = 117.66\times 2.5=294.15j

Now according to work energy theorem work done is equal to change in kinetic energy

So \frac{1}{2}mv^2=294.15

\frac{1}{2}\times 11\times v^2=294.15

v =7.31 m/sec

So velocity final velocity will be 7.31 m/sec

Based on Newton's law of action-reaction, which arrow represents the force that the seat belt would exert on the man's body if h
Alenkasestr [34]

Answer:

c. Y

Explanation:

Newton's third law of motion states that action and reaction are equal and opposite. Hence for every action, there is an equal and opposite reaction.

Considering the system of forces shown in the image, W and Y are  opposite forces. When the driver slams on the brakes, he will be pushed forward towards the windscreen. The force Y exerted by the seat belt keeps him on the drivers seat by moving him backwards towards the seat.
