B. Accelerating a bowling ball from rest to 35 m/s
Explanation:
Accelerating a bowling ball from rest to 35m/s will require more impulse compared to a baseball.
Impulse is the force acting on a body a particular period of time. It is similar to momentum.
When impulse is applied on a body, it change it state from rest and cause motion.
A body with more mass will require a higher impulse to cause it to accelerate. Bowling balls are heavier. They require more impulse to make them move.

Answer:
9.4 m/s
Explanation:
According to the work-energy theorem, the work done by external forces on a system is equal to the change in kinetic energy of the system.
Therefore we can write:
where in this case:
W = -36,733 J is the work done by the parachute (negative because it is opposite to the motion)
is the initial kinetic energy of the car
is the final kinetic energy
Solving,
The final kinetic energy of the car can be written as
where
m = 661 kg is its mass
v is its final speed
Solving for v,
Scalar quantities have only magnitude. example temperature, distance.
Vector quantities have magnitude and direction.Example force, velocity.
You can say "I applied a force p\of 3 newtons to the left" but you can't say I added 32 Fahrenheit to the left
