A 75.0-kg ice skater moving at 10.0 m/s crashes into a stationary skater of equal mass. After the collision, the two skaters move as a unit at 5.00 m/s. Suppose the average force a skater can experience without breaking a bone is 4 500 N. If the impact time is 0.100 s, does a bone break?
A 25.0-gram bullet enters a 2.35-kg watermelon with a speed of 217 m/s and exits the opposite side with a speed of 109 m/s. If the melon was originally at rest, then what speed will it have as the bullet leaves its opposite side? (CAUTION: Be careful of the units on mass.)
A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg.If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m. How fast is the coyote moving when he has traveled 2.11m while he is slowing down? Assume his initial speed when he is slowing down is equal to his final speed when the rockets were firing.
Suppose a cyborg shoots Monkey D. Luffy with 3g bullets at a rate of 100 bullets/min, with speed of each bullet is 500 m/s. The bullets rebound straight back from luffy's body with no change in speed. What is the magnitude of the average force on luffy's body? (Answer in whole number, no unit)
) A car with mass 996 kg moving at 28 m/s hits a giant bag of marshmallows. The bag slows the car down, but it is unable to completely stop it because it ruptures at Dt = 1.8 s after the car hits, scattering marshmallows all over the countryside. Suppose the bag exerts a force on the car that depends on time (t) given by F = -At2; A = 7.2 x 103 N/s2 when t is in seconds from the moment the car hits the bag (t = 0) until the moment the bag ruptures. What is the speed of the car after the bag ruptures? (answer: 14 m/s)
A 1500 kgkg car skids to a halt on a wet road where μkμkmu_k = 0.55. You may want to review (Pages 141 - 145) . How fast was the car traveling if it leaves 60-mm-long skid marks? Express your answer to two significant figures and include the appropriate units.
You are the design engineer in charge of the crashworthinessof new automobile models. Cars are tested by smashing theminto fixed, massive barriers at 45 km/h A new model of mass1500 kg takes 0.15 s from the time of impact until it is broughtto rest. (a) Calculate the average force exerted on the car bythe barrier. (b) Calculate the average deceleration of the carin g’s.
In an intersection, a bus moving at (100i) m/s and a truck moving at (200j) m/s collided with each other. Assuming that the two objects have the same mass, what would be their final speed together? Note: i and j are unit vectors CHOICES: - 300 m/s - 173.21 m/s - 100 m/s - 223.61 m/s
A crane drops a 1.9 kg steel ball onto a steel plate. The ball's speeds just before impact and after are -7.7 m/s and 4.8 m/s, respectively. If the ball is in contact with the plate for 0.016 seconds, what average force does the ball exert on the plate during impact?
A 0.55-kg croquet ball is initially at rest on the grass. When the ball is struck by a mallet, the average force exerted on it is 270 N. If the ball's speed after being struck is 5.1 m/s, for what amount of time was the mallet in contact with the ball? I solved this and got 0.0104 but mastering physics is saying that my answer is not correct.
A 15,000[kg] railroad car A traveling at a speed of 24.0 [m/s] strikes an identical car B at rest. If the cars lock together as a result of the collision, what is their common speed just afterward? Please give your answer in units of m/s, however, do not explicitly include units when typing your answer into the answer box. Including actual units will result in your answer being incorrectly scored.
Billy and Joe are doing science experiments in the skating rink at SM Mall of Asia. Billy of mass equal to 80kg was pushed and slid due east, and Joe with mass equal to 50kg was pushed towards north. After the collision, Billy is observed to move N 37° of E with a speed of 6m/s. Also, Joe is observed to move at S 67° E with a speed of 9m/s. If the rink is assumed to be frictionless, by how much did the total kinetic energy of the two people decrease after the collision?
