A stationary 90 kg baseball pitcher throws a 0.15 kg baseball forward
at 40 m/s. What is the linear momentum of the baseball?
Select one:
0.0038 kg . m/s
3600 kg. m/s
267 kg . m/s
6 kg. m/s

momentum = 6kgm/s

Explanation:

given that the baseball pitcher is at stationary position, his velocity will be equal to zero. If velocity is zero, his linear momentum will therefore equal to zero.

Linear momentum is the product of mass and velocity. Given that the baseball has

Mass M = 0.15 kg

Velocity V = 40 m/s

Momentum = MV

Momentum = 0.15 × 40 = 6 kgm/s

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

the total distance traveled by the car is

30km + 49km = 79 km .
