What object has more momentum a car traveling at 10 kilometers and hours or a baseball pitched at 150 kilometers and hour?
car 1500 kilograms
Baseball 150 grams
cars energy = 1/2 x 1500 x (10/3.6)2
= 5,787 joules
baseballs energy = 1/2 x 0.15 x (150/3.6)2
= 130 joules
(i worked it out for energy then noticed it said momentum)
car = 1,500 x 10/3.6 = 4,166.67 kgm/s
baseball = 0.15 x 150/3.6 = 6.25 kgm/s
the car

How fast is 58 Kilometers an hour?
58 km an hour is just under 1 metre (0.966...m ) per minute. How fast that is depends on the context. It is far faster than a human being could run for any sustained period but less than half the speed of the ball served by a tennis player, or bowled in cricket or pitched in baseball. It is much faster than urban speed limits in the UK but only about half the motorway speed limit (again in UK). It is nowhere near fast enough for a plane to stay airborne and is positively crawling compared with electromagnetic radiation in a vacuum (1,080,000,000 km per hour).
