A cart, which is moving at a speed of 20 m / s, starts to suffer a force resulting from intensity 60 N, in the same direction and in the opposite direction to the speed. Knowing that F = ma, Where F is force, m is mass and a is acceleration. It appears that, after a time interval of 5.0 s, the speed is 5.0 m / s. The mass of the cart, in kg, is:Choose one:The. 50B. 20ç. 30d. 10e. 40
Sweden and Norway are at war over who makes the best pickled herring. You are in charge of a Swedish artillery unit that is trying to shoot at some Norwegians located 1000 meters away at the same height as you are. If we neglect the friction of the air, the cannon ball follows a parabolic trajectory; as you certainly recall from prior courses, a cannon ball travels a distance L = V²sin(2a) 9 where V is the initial velocity, a is the angle of the cannon barrel, and g = 9.8 m/s² is the gravitational acceleration. You realize that you only have two options for how to shoot. Option (I) is to use 1 bag of gun powder, which produces an initial velocity of exactly V₁ = 105 m/s, and to try to set the angle to aI,nominal = 39 degree. Option (II) is to use 2 bags of gun powder, which produces exactly VII = 137 m/s, and to try to set the angle to aII,nominal = 15 degree. If you set the angles exactly to the nominal ones, compute the traveling distances. L₁ = LII = The problem is that the cannon…

A 10kg object is dropped from rest from the top of a 100m cliff. Exactly one second later, an 8g bullet is fired upward from the ground with a muzzle velocity of 300(m)/(s). Assume an inelastic collision occurs between the two objects. How long after the 10kg object is dropped will the combined object hit the ground? Compare that time to the time for the 10kg object to hit the ground without the collision.
Q20. A 2-lb ball B is traveling around in a horizontal circle of radius r₁= 5.8 ft with a speed (VB)₁ = 3.4 ft/s. If the attached cord is pulled down through the hole with a constant speed v₁ = 1.1 ft/s, determine how much time is required for the ball to reach a speed of 14 ft/s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. B 1 (VB)1 Your Answer: Answer Vr units
