1.A roller coaster car rapidly picks
up speed as it rolls down a
slope. As it starts down the
slope, its speed is 4 m/s. But, 3
seconds later, at the bottom of
the slope, its speed is 22 m/s.
What is its average acceleration?
Final speed – initial speed

1.You and your friend are goofing around
in the hall. You take off running and as
you turn a corner you run into the back
of the principal (uh-oh), with a force of
256 Newton’s. The principal has a mass
of 64 kg, at what rate did you
accelerate your principal?

1. A cow with a mass of 1090 kg, was peacefully eating grass, when a beam of
light lifted it with a force of 49,050 Newton’s up to a UFO. Due to its lack of
intelligence, it was put back the next morning when the aliens assumed it was
the dominated species on the planet, thereby preventing an intergalactic war.
At what rate did the cow accelerate towards the UFO?

1.While driving to a party,
the car in front of you

accelerates his large
obnoxious truck, which
happens to weigh 1950 kg,
to a rate of 8 m/s2 . What
force was exerted on to
the truck?

1.A baby with a mass of 16 kg gets loose
in a gym, where other kids are playing
with exercise balls. One kid unaware
of the rogue baby kicks a ball with a
force of 304 Newton’s. At what rate
will the baby accelerate when the ball
connects? The baby will land safely in
a pile of ultra soft padding, unharmed
but a little confused.
