What net external force is exerted on a 1100-kg artillery shell fired from a battleship if the shell is accelerated at 2.40 x 10^4 m/s^2 ? What force is exerted on the ship by the artillery shell?

A 115kg rugby player is initially running at 5.5 m/s in the + direction, but collides with a goalpost and experiences a backward force of 1.71 × 10^4 N for 5.25 × 10^-2 s. what is the final \velocity of the rugby player in the horizontal direction

A hockey player slaps a puck into a cushion, which brings the puck to rest.  If the puck's initial velocity was +40 m/s and it has a mass of 170 g, what force does the cushion apply to the puck?  Assume the cushion acts on the puck for 0.03 s and the surface that the puck slides on is frictionless.

A freight train consists of two 8.00×104 kg5.60×104 kg engines and 45 cars with average masses of 5.50×104 kg5.50×104 kg. (a) What force must each engine exert backward on the track to accelerate the train at a rate of 4.00×10−2 m/s if the force of friction is 6.20×105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently trains are very energy-efficient transportation systems. (b) What is the force in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines?

Problem 5: a) What is the magnitude of the net external force exerted on a 1200 kg artillery shell that's accelerated from a battleship's large gun at 2.2 × 104 m/s²? b) What is the magnitude of the force exerted on the ship by the artillery shell?

An advertisement claims that a particular automobile can "stop on a dime". What net force would be necessary to stop a 950 kgkg automobile traveling initially at 57.0 km/hkm/h in a distance equal to the diameter of a dime, 1.8 cmcm?

Michael fell asleep while driving home from school. His 1255 kg car hit a guardrail while moving at 15.98 m/s. The guardrail exerted a 6.110E4 N force on the car for 0.1233 s. After the car hit the guardrail, how fast was it moving?

A golf ball of mass 4.50x10^-2 kg is struck by a club. Contact lasts 2.00x10^-4 s, and the ball leaves the tee with a horizontal velocity of 50.0 m/s. Compute the average force the club exerts on the ball by finding its average acceleration.

A high-speed photograph of a club hitting a golf ball is shown in the figure below. The club was in contact with a ball, initially at rest, for about 0.0024 s. If the ball has a mass of 55 g and leaves the head of the club with a speed of 1.9 x 102 ft/s, find the average force (in kN) exerted on the ball by the club. kN

A bullet is accelerated down the barrel of a gun by hot gases produced in the combustion of gun powder. What is the average force (in N) exerted on a 0.0500 kg bullet to accelerate it to a speed of 675 m/s in a time of 5.00 ms (milliseconds)? (Enter the magnitude.)
