A man in a sled with a total mass of 125kg, slides down a grassy hill and reach a speed of 8 m/s at the bottom. if a pile of grass can exert a constant force of 250n, how long will the sled stop?

Sagot :

Answer:

The time it would take for the sledge to stop will be 4 seconds.

Explanation:

From newton second law:

F=ma

Recall the formula for acceleration is:

The equation would then become:

Replace v=8 ,m=125 and F=250 into the above equation:

Calculate the value of t.

The time it would take for the sledge to stop will be 4 seconds.
