In a game of egg-toss, you and a partner are throwing an egg back and forth trying not to break it. Given your knowledge of mome
lutik1710 [3]
F=dP/dt.  So you want the momentum to change as slowly as possible in time to minimize the force.  So as you catch the egg, let your hand move backward with it for awhile, slowly bringing it to a stop.  If you hold your hand steady when you catch it the force due to the impact could break it.

A 20-lb force acts to the west while an 80-lb force acts 45° east of north. The magnitu 80 lb 70 lb 067 lb 100 lb
natulia [17]

Answer:

option C

Explanation:

given,

force act on west  = 20 lb

force act at 45° east of north = 80 lb

magnitude of force = ?

∑ F y  =  80 cos 45⁰

    F y =  56.57 lb

magnitude of forces in x- direction

∑ F x = -20 + 80 sin 45⁰

        = 36.57 lb

net force

F = \sqrt{F_x^2+F_y^2}

F = \sqrt{56.57^2+36.57^2}

F = 67.36 lb≅ 67 lb

hence, the correct answer is option C

An object with a mass of 25 kg object is moving at 30 m/s. What is the
Pani-rosa [81]

Answer: 750 kgm/s

Explanation:

Mass of object = 25 kg

Speed by which object moves =30 m/s. Linear momentum of the object = ?

Since momentum refers to the quantity of motion of the moving object,

Linear momentum = Mass x Speed

= 25kg x 30m/s

= 750 kgm/s

Thus, the linear momentum of the object is 750 kgm/s
