Question

What is the mass of an object that needs a force of 6000 newtons to increase its speed from rest to 107 m/s in 2.3 seconds?

Answer 1

m=141,87 kg

Explanation:

a=ΔvΔt=vf−vitf−ti

a=107−02,3−0

a=1072,3

a=46,52 ms2 acceleration of object

F=m⋅a Newton's second law

F=6600 N
a=46,52 m/s^2
m=?

6600=m⋅46,52

m=660046,52

m=141,87 kg
