Question

ALL OF MY POINTS FOR THIS!

An automobile with a mass of 1127 kg accelerates at a rate of 6 m/s² in the forward direction. What is the net force acting on the automobile?
N

What is the momentum of a 69-kilogram ice skater gliding across the ice at a speed of 6 m/s?
kg-m/s

Answer 1

Newton's 2nd law of motion:

Force = (mass) x (acceleration)

= (1,127 kg) x (6 m/s² forward)

= (1,127 x 6) newtons forward

= 6,762 newtons forward
______________________________

Momentum = (mass) x (speed)

= (69 kg) x (6 m/s)

= 414 kg-m/s
