Question

if a 60 kg person on a 15 kg sled is pushed with a force of 300n what will be the persons acceleration

Answer 1

Answer:

A Newton has units of kgm/s² . We'll come back to this shortly.

The 300N of force are acting on 60kg+15kg=75kg of mass. F=ma , so a=F/m .

a=300kgm/s² / 75kg=4ms2 .

Since Earth's gravity is approximately g≈0.98m/s² , the acceleration is approximately 0.42g .

OR

If the net force is 300n then you'd just use the equation

F=m×a

So

300N=75kg×a

Which can be written as

a=300kg⋅m/s275kg

a=4m/s2

Answer 2

Answer:

F=m.a ....5

Explanation:

neglect the sled weight just man weight 60 kg only...you will get the answer 5 as acceleration
