# Chapter 4 - Dynamics: Newton's Laws of Motion - Problems: 3

1450 N.

#### Work Step by Step

Use Newton’s second law to find the required net force in the horizontal direction, which is the tension. The answer is rounded to 3 significant figures. $$\Sigma F=ma=(1210 kg)(1.20 \frac{m}{s^{2}}) \approx 1450 N$$
