A car of mass 1000 kg is moving with a velocity 20m /s on a horizontal straight road. If the driver applies brakes to produce a constant breaking force of 5000 Newton, the acceleration of the car i s ..... m /s^(2).

Answer»

`-5`
50
5
none

Solution :FromNewton.ssecondlaw ofmotion
F= ma HereF=breakingforce
`=-500 N`
ACCELERATION`a= (F )/( m ) = (5000)/( 1000) =0 5 MS^(2)`
