A FOOTBALL PLAYER RUNS ACROSS THE 30 YARD LINE AT AN ANGLE. HE CONTINUES IN A STRAIGHT LINE AND CROSSES THE GOAL LINE AT THE SAME ANGLES. DESCRIBE TWO PARALLEL LINES AND A TRANSVERSAL IN THE DIAGRM
A football player runs for a distance d1 = 8.55 m in 1.33 s, at an angle of θ = 62.1degrees to the 50-yard line, then turns left and runs a distance d2 = 10.68 m in 2.19 s, in a direction perpendicular to the 50-yard line. The diagram shows these two displacements relative to an xy coordinate system, where the x axis is parallel to the 50-yard line, and the y axis is perpendicular to the 50-yard line. What...
A football player is at the 50-yard line when the timer is started. He is at the 40-yard line after 1 second, the 30-yard line after 2 seconds, the 20-yard line after 3 seconds and the 10-yard line after 4 seconds. His acceleration is ____. a) negative b) zero c) a constant non-zero value d) changing
A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 2.0 m/s, skates by with the puck. After 1.20 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.40 m/s2, determine each of the following. (a) How long does it take him to catch his opponent? (Assume the player with the puck remains in motion at constant speed.) s (b)...
