(25 pts) Thre 12.5 m/s at 35.00 e boats are moving on a lake. The first boat (m - 2570 kg) is moving at south of west. The second boat (m- 1560 kg) is moving at 9.65 m/s at 30 west of north. The third boat...
A 1570 kg car moving south at 10.6 m/s collides with a 2640 kg car moving north. The cars stick together and move as a unit after the collision at a velocity of 5.60 m/s to the north. Find the velocity of the 2640 kg car before the collision. Assume that North is positive.
An object (A) of mass m A = 29.0 kg is moving in a direction that makes angle of 40° north of east with a speed v A = 5.10 m/s, while object (B) of mass m B = 17.5 kg is moving due north with a speed v B = 7.85 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision. An...
An object (A) of mass mAA = 27.5 kg is moving in a direction that makes angle of 56° south of east with a speed vAA = 5.00 m/s, while object (B) of mass mBB = 17.5 kg is moving due north with a speed vBB = 8.00 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision.
An object (A) of mass mA = 29.5 kg is moving in a direction that makes angle of 30° north of east with a speed vA = 5.20 m/s, while object (B) of mass mB = 18.0 kg is moving due south with a speed vB = 8.00 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision.
On an icy road, a 1600-kg car moving north at 23 m/s collides with a 2400-kg car moving east at 16 m/s. The two cars stick and move together. Let east be the x direction, and north be the y direction. What is the y-component of the velocity of the wreckage after the collision?
A 1200-kg car is moving at 19 m/s due north. A 1500-kg car is moving at 18 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. Determine the speed and direction of the combined two-car wreck immediately after the collision. direction North of East
A 1100-kg car is moving at 20 m/s due north. A 1600-kg car is moving at 19 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. Determine the speed and direction of the combined two-car wreck immediately after the collision. magnitude=? direction=?
. Two ice skaters collide on the ice. A 39.6-kg skater moving South at 6.21 m/s collides with a 52.1-kg skater moving East at 4.33 m/s. The two skaters entangle and move together across the ice. Determine the magnitude and direction of their post-collision velocity
A 3 30 kg boats sailing 10 Oe north of east at a speed of 1.60 m s. 31 0 s later, it is sailing 30.0° north of east at a speed of 3.50 m/s. During this time, three forces act on the boat: a 34.4-N force directed 10.0e north of east (due to an auxilary engine), a 20.9-N force directed 10.0° south of west (resistance due to the water), and E (due to the wind). Find the (a) the...
