Question

How much force is needed to accelerate a 2000-kg car at 5 meters per second per second? A. 400 N B. 500 N C. 1000 N D. 10000 N

Answer 1

D. f=ma
therefore, f= 5*2000= 10000N

Answer 2

Answer:

Answer:10000n

Explanation:

Answer:

F = 10 000 N

The force necessary would b  10 000  Newtons

Explanation:

Using Newton's Second Law that Force is equal to mass times acceleration,  

F = m a

and assuming we are not dealing with friction as we have no coefficient of static friction we can set up ar equation as

F = ?

m = 2000 k g   a =5m/s/s F =(2000 kg   )5 m /s/s

F = 10 000 N
