A 1490-kg car is moving due east with an initial speed of 29.5 m/s. After 9.14 s the car has slowed down to 18.8 m/s. Find the magnitude of the net force that produces the deceleration.

The magnitude of the net force that produces the deceleration = 1744 N

Explanation:

Using the equations of motion, we can find the deceleration of the car and thereby find the magnitude of the met force that produces such deceleration

v = u + at

where v = final velocity = 18.8 m/s

u = initial velocity = 29.5 m/s

t = 9.14 s

a = ?

v = u + at

18.8 = 29.5 + 9.14a

9.14a = 18.8 - 29.5 = -10.7

a = - 1.171 m/s²

Magnitude of Force causing deceleration = ma = 1490 × 1.171 = 1744 N

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

mass and volume are the answers you are looking for
