Show the velocity graph of a 4.7 kg object as it moves along the x-axis

[Cb8]

Homework Statement

Figure 1 shows the velocity graph of a 4.7 kg object as it moves along the x-axis.
A) What is the x- component of the net force acting on this object at t = 1s?
B) At 3s?
C) At 7s?

Relevant Equations

F=M•a

If force= m•a would the answer just be the y-axis • 4.7 at the specific time such as
A) 4.7 • 6 = 28.2?
B) 4.7 • 12= 56.4
C) 4.7 • 3 = 14.1

Post Figure 1. (If you have a velocity-time graph, how would you find the acceleration at any point?)

I solved it! Sorry for the late response, if you’re still wondering.

B) 4.7 • 12= 56.4
C) 4.7 • 3 = 14.1

Since the y-axis shows velocity (in m/s) multiplying the y-axis by the mass of 4.7 (in kg) yields momentum (in kg m/s).

A relevant equation would be: $F=\frac{dp}{dt}$
