Explanation:
Vnet = 0.4m/s - 3.0m/s = - 2.6m/s
so the man walks 2.6m/s towards the west
Answer:
The acceleration is 2 m/s2.
Explanation:
We calculate the acceleration (a), with the data of mass (m) and force (F), through the formula:
F = m x a ---> a= F/m
a = 40 N/20 kg <em> 1N= 1 kg x m/s2</em>
a= 40 kgx m/s2/ 20 kg
<em>a= 2 m/s2</em>
I believe it’s A. I know for sure it isn’t D.
The last one is correct (D)
