A net force of 15 N is applied to a cart with a mass of 2.1 kg. a. What is the acceleration of the cart? b. How long will it tak
e the cart to travel 2.8 m, starting from rest?
1 answer:
The first question's answer is :
If, F=ma
Then, 15N= 2.1kg (a)
15/2.1=a
7.14=a
Therefore, acceleration = 7.14m/s^2
sorry I am not sure about the second question :-(

I think the answer is B because juice has a higher density than water
Answer:
0.018kg
Explanation:
Q=mlf
m=?,Lf=334000J/kg,Q=5848J
5848=mx334000
5848=334000m
divide both sides by 334000
334000m/334000=5848/334000
m=0.018kg
