Question

an object with mass 5 kg moves at a constant velocity of 8 m/s. a constant force then acts for 6 seconds on the object giving it a speed on the object giving it a speed of 4 m/s in opposite direction. the acceleration produced is?

Answer 1

Explanation:

acceleration ir rate of change of velocity.

acc = (final velocity - initial velocity) / time

acc= (-4-8)/6

= -12/6

= -2 m/s²

additionally, Force = mass * acceleration

F= 5*(-2) = -10 N

Answer 2
