Calculate the final speed (in m/s) of a 114 kg rugby player who is initially running at 7.25 m/s but collides head-on with a padded goalpost and experiences a backward force of 1.75 ✕ 104 N for 6.50 ✕ 10−2 s.
Calculate the final velocity right after a 117-kg rugby player who is initially running at 7.55 m/s collides head-on with a padded goalpost and experiences a backward force of 1.85 times 10^4 N for 5.50 times 10^-2 s.
Calculate the final velocity right after a 118 kg rugby player who is initially running at 7.45 m/s collides head-on with a padded goalpost and experiences a backward force of 17500 N for 5.50 x 10-2 s. Question Credit: OpenStax College Physics final velocity: m/s
A 190-kg rugby player running east with a speed of 4.00 m/s tackles a 99.0-kg opponent running north with a speed of 3.90 m/s. Assume the tackle is a perfectly inelastic collision. (Assume that the +x axis points towards the east and the +y axis points towards the north.) (a) What is the velocity of the players immediately after the tackle? magnitude m/s direction ° counterclockwise from the +x axis (b) What is the amount of mechanical energy lost during...
A 135-kg rugby player running east with a speed of 4.00 m/s tackles a 92.5-kg opponent running north with a speed of 4.4 m/s. Assume the tackle is a perfectly inelastic collision. (Assume that the +x-axis points towards the east and the +y-axis points towards the north.) I got the answer to part A: (a) What is the velocity of the players immediately after the tackle? magnitude 2.97 m/s direction 37 degrees counterclockwise from the +x-axis I don't understand how...
A 3.24 kg object initially moving in the positive x-direction with a velocity of +5.15 m/s collides with and sticks to a 1.66 kg object initially moving in the negative y-direction with a velocity of -2.54 m/s. Find the final components of velocity of the composite object. (Indicate the direction with the sign of your answer.) Vfx = ? Vfy = ?
A rugby player carries the ball 15.9 m straight clown the playing field in 3.46 s. He then passes the ball 2.66 m straight backward to a teammate in 0.293 s. The teammate runs the ball straight forward another 17.6 m in 3.68 s before being tackled. Calculate the ball's average velocity for each of the three intervals and for the entire motion. Let the positive direction be down the field. Average velocity during the first 3.46 seconds: m/s Average...
Mass 1 of 8 kg is initially moving at 10 m/s in the +x direction and it collides perfectly elastically with mass 2 of 3 kg initially at rest. What is the final velocity of mass 2 after the collision in m/s? (Note: the masses are not needed to answer this question.) _______
A softball of mass 0.220 kg that is moving with a speed of 6.5 m/s (in the positive direction) collides head-on and elastically with another ball initially at rest. Afterward it is found that the incoming ball has bounced backward with a speed of 4.3 m/s. (a) Calculate the velocity of the target ball after the collision. m/s (b) Calculate the mass of the target ball. kg
(10%) Problem 4: A wad of clay m/=0.33 kg is thrown in the x direction with an initial velocity of v = 29 m/s.
