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...
(non calculus physics) A college fullback weighing 100 kg is running north at a speed of 4.5 m/s when he is tackled by a 110 kg linebacker running east at 3.5 m/s. Assume the collision is perfectly inelastic. Find the velocity of the players just after the tackle. Find the kinetic energy lost as a result of the collision. How do you account for this apparently “lost” energy?
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...
please help with the breakdown of units
Constants A 86-kg fullback is running at 3.6 m/s to the east and is stopped in 0.85 s by a head-on tackle by a tackler running due west. Calculate the original momentum of the fullback Express yodiSanswer to two significant figures and include the appropriate units. Enter positive value if the direction of the momentum is to the east, and negative value if the direction of the momentum is to the west.
In a rugby match, a 97kg player who runs east at a speed of 2.1m/s is reached by a 113kg opponent who runs north at a speed of 2.1m/s. If the collision was perfectly inelastic, what is the magnitude of the mechanical energy lost as a result from the collision?
Hank, who is twice the mass of Marcia, is running east at 2.0 m/s. Marcia is running north at 1.8 m/s. They collide and stick. Immediately after the collision, what is their speed?
A fullback with a mass of 100 kg and a velocity of 3.0 m/s due west collides head-on with a defensive back with a mass of 86 kg and a velocity of 4.5 m/s due east. (Take the positive direction to be to the west.) (a) What is the initial momentum of each player? momentum of full back kg · m/s momentum of defensive back kg · m/s (b) What is the total momentum of the system before the collision?...
