Question

A car mass of one metric ton accelerates from rest at the rate of 2m/s^2 from t = 0 sec to t = 10 sec. There after it travels with a uniform velocity. The measure of net retarding force acting on the car after 10 secs is

A) 4000 N
B) 2000 N
C) 0 N
D) -2000 N​

Answer 1

Answer:

c)0N

because in uniform velocity ,a=0

Answer 2

Answer:

4000N

Explanation:

The right answer is surely 4000N
