- Kara Moore was applying make up in the parking lot Unaware that Lisa's car was stopped in her lane 30 ft ahead. Kara rear ended Lisa's car. Kara's 1300 kg car was moving a 11m/s and completerly stopped after hitting Lisa;s car in 0.14 sec. What is the magnitude of the force experienced by Kara's car?A young girl is riding a bicycle that has a total mass (including the kid) of 21.2 kg. The girl is moving at 5.99 m/s on a flat road when suddenly she slams on the brakes and skids to a stop in 8.22 meters. What was the magnitutde of the average force due to friction acting on the bicycle? Remeber, the magnitude of a force is always positive. Assume a constant friction force measured in Newtons and 3 significant digits in your answer.A 72.5-kg person is riding in a car moving at 18.5 m/s (assume this is the positive direction) when the car runs into a bridge abutment. This problem will illustrate why the invention of the airbag dramatically improved the safety of automobiles. a. Calculate the horizontal component of the average force, in newtons, on the person if he is stopped by a padded dashboard that compresses an average of 0.85 cm. b. Calculate the horizontal component of the average force, in newtons, on the person if he is stopped by an air bag that compresses an average of 16 cm?
- A 50 N net force acts right on a 20 kg object. Given the initial velocity of the object is 10 m/s left, find the velocity after the net force has acted for a time of 8 secondsA 47 kg skater is standing still in front of a wall. By pushing against the wall she propels herself backwards with a velocity of -1.1 m/s. Her hands are in contact with the wall for 1 seconds. Ignoring friction and wind resistance, find the average force she exerts on the wall? FaverageA constant net force of 300N is applied to accelerate a cart in a frictionless surface from rest to a velocity of 30 m/s in 5s. What is the mass of the cart? 2. A 0.15 - kg baseball approaches a baseball bat at 30 m/s. If it is in contact with the baseball bat for 0.003 s, what is the average contact force between the ball and the racket? Ignore the air resistance.
- 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.A 3.00-kg object is initially moving northward at 15.0 m/s.

At the end of the 6.00 s, what is magnitude of the object’s final velocity?A baseball player hits a bunt during which the bat is in contact with the ball for 0.0005 s. If the bat applies a force of 3,000 N to the 0.15 kg baseball, what is the change in the ball's velocity? Your answer should be in units of m/s but you should only submit the number for your answer (and don't worry about negative signs, just use a positive value).
- 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 1,000 kg car traveling at 40 m/s collides with a brick wall.
