A 1600N force is applied to a 85kg mass what is the acceleration of the mass?

1 answer:

4 0

Newton 3rd law:
F=ma
1600=85*a
1600/85=a
a=18.82 m/s^2

Answer:

$I = -2.1 kg.m/s$

Explanation:

Given,

mass of the object,m = 0.30 Kg

initial speed, v_i = 3 m/s

time of collision = 0.20 s

final speed, v_f = -4 m/s

Impulse = change in momentum

$I = m (v_f-v_i)$

$I = 0.30\times (-4-3)$

$I = -2.1 kg.m/s$

Hence, impulse of the object is equal to $I = -2.1 kg.m/s$

They should be bigger as if it is hot the tracks will expand as it is made of metal and then there is more room for it to expand or contract
