<u>Answer</u>
You should still ensure you are steering straight in the direction of skidding.
Take your foot off the brake unless you are about to hit something. steer in the direction of the skid to straighten your car.
Kinetic energy =(1/2) (mass) (speed²)
First object: KE = (1/2) (2 kg) (2m/s)² = 4 joules during the lift.
Second object: KE = (1/2) (4kg) (3 m/s)² = 18 joules during the lift.
The second object has more kinetic energy while it's being lifted
than the first object has while it's being lifted. Once they reach their
final heights and stop, neither object has any kinetic energy.
First find the time it takes for the ball to reach the ground using the vertical component of its position vector:
Meanwhile, the horizontal component of the ball's position vector is
After about 4.52 s, the ball has traveled a horizontal distance of
which you would round to 200 m, so the answer is B.
