Question

A student pushes a loaded sled whose mass is 240 kg for a distance of 2.3 m over the

frictionless surface of a frozen lake. He exerts a horizontal force equal to 130 N. If the sled starts from

rest, what is its final velocity ?​

Answer 1

Answer:

i think it's 105.

Explanation:

Answer 2

Explanation:

m=240kg

S=2.3m

u=0

v=?

Now,

F=ma

130=240Xa

a=240/130

a=1.8m sq.

Then,

v sq. =u sq. +2aS

v sq. =0+2X1.8X2.3

v sq. =2X4.1

v=sq.root of 8.2

v=2.9(approximately)
