What net external force is exerted on a 1350-kg artillery shell fired from a battleship if the shell is accelerated at 1.80 ✕ 104 m/s2? (Enter the magnitude.)  N What is the magnitude of the force exerted on the ship by the artillery shell?  N

O as shown A block of mass m enters a rough surface at x = in the figure with an initial speed of vo. Coefficient of kinetic friction in this region varies as Hx How can magnitude of the acceleration of the block be expressed as a function of x? bx where b is a constant. y vo X-0 Seçtiğiniz cevabın işaretlendiğini görene kadar bekleyiniz 5,00 Puan a = 2bgx = bgx a = 2gx a = gx a = 2bx

A 1370 kg jeep traveling at 19 m/s can be stopped in 24.0 s by gently applying the brakes. a) What is the average force exerted on the jeep in this case? b) If the driver slams on the brakes, the jeep stops in 2.10 s. What is the average force exerted on the jeep in this case? c) How much time will it take it stop if the driver coasts and lets a 300 N friction force stop the car?

A(n) 878 kg drag race car accelerates from rest to 102 km/h in 0.962 s. What average force is exerted on the car?Answer in units of N.

a a resistive force of magnitude (kmv - ma) N, where k and a are constants. (a) Show that dv (a – kv) dt %3D (b) If vo is the speed of the particle at time t = 0 s, show that: 1 kvo t In k a - kv

A horse pulls a wagon, and the wagon pulls back with the same force (according to Newton's 3rd Law). How do they get anywhere? O They were already moving with a constant velocity. O They don't; the forces cancel. The ground exerts a force on the horse. O The force exerted by the horse is greater than that by the wagon. O The forces don't cancel while they accelerate - only when they are moving at constant velocity.

A 958-kg car starts from rest on a horizontal roadway and accelerates eastward for 5.00 s when it reaches a speed of 35.0 m/s. What is the average force exerted on the car during this time? kN eastward

Which of the following statements is incorrect? O Forces are vectors O An object in at rest will have no applied force at all on it. O An object accelerating in a certain direction will have a total force in the same direction. O An object at a constant velocity will have no net force on it. s

A 3.196E+3-kg Chevy Suburban on route 422 is stopped at the light in Annville heading eastbound. After the light turns green, the driver puts the pedal to the floor. The engine provides a monstrous 1.647E+4 N of forward force on the Suburban. The vehicle passes by the Allen Theatre at 11.3 m/s. Air resistance and friction contribute a 2.544E+3 N force that opposes the motion. Find out how far (in m) the suburban travels in the 3.80 s after it passes the Allen Theatre.

The 2.8-kg particle moves in the horizontal x-y plane and has the velocity shown at time t = 0. If the force F = 2.80 + 0.65t2 newtons, where t is time in seconds, is applied to the particle in the y-direction beginning at time t = 0, determine the velocity v of the particle 3.6 seconds after F is applied.
