A competitive mini-golf player notices an opponent's ball situated 50cm in front of a wall containing two tunnels. One tunnel leads to the hole, the other to a bunker. The player skill fully putts their ball due East at the opponent's ball with a velocity of 4m/s.
The opponent's ball is knocked 20° to the South of East with a velocity of 1.7m/s into the tunnelleading to the bunker. Meanwhile the player's ball travels into the second tunnel located North of East (to great applause from spectators).
If the player's ball weighed 40g, and the opponent's ball weighed 45g, how far apart were the centres of the two tunnels?
Two rockets having the same acceleration start from rest, but rocket A travels for twice as much time as rocket B, If rocket A reaches a speed of 390m/s , what speed will rocket B reach
A coil with an inductance of 14.5 H and a resistance of R = 4.0 ohms is suddenly connected to a resistanceless battery with E = 184.2 V. What is the equilibrium current
Then, a thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2 = 0.100 N. Using this information, find the initial charge on each sphere, q1 and ..
A cart of mass M = 1.6 kg can roll without friction on the level track. A light string draped over a light, frictionless pulley connects the cart to a hanger with mass m = 0.7 kg.
A rocket of total mass 3180-kg is travelling in outer space with a velocity of 115 m/s toward the Sun.
