Question

1. a 1000 kg car accelerates at 2 m/s². what is the net force exerted on the car? (a) 500 n (b) 1000 n (c) 1500 n (d) 2000 n (e) none of above

Explanation:

Step1: Recall Newton's second law

$F = ma$

Step2: Substitute given values

$m = 1000$ kg, $a=2$ m/s², so $F=1000\times2$

Step3: Calculate the force

$F = 2000$ N

Answer:

D. 2000 N
