Question

1. An object with a mass 10 kg moves at a constant velocity
of 10 m/s. A constant force then acts for 4 seconds on
the object giving it a speed of 2 m/sin opposite direction.
The acceleration produced is
1. 3 m/s2
2. -3 m/s2
3. 0.3 m/s2
4. -0.3 m/s2
10​

Answer 1

Answer:

2

Explanation:

apply first equation of motion

and take final velocity negative becz both are in opposite directions

thn solve it
