At the intersection of Texas Avenue and University Drive, a yellow, subcompact car with mass 800kgtraveling east on University collides with a maroon pickup truck with mass 1850kg that is traveling north on Texas and ran a red light. The two vehicles stick together as a result of the collision and, after the collision, the wreckage is sliding at16.0 m/s in the direction 24.0? east of north. The collision occurs during a heavy rainstorm; you can ignore friction forces between the vehicles and the wet road.
A. Calculate the speed of the car before the collision.
B. Calculate the speed of the truck before the collision.
For the cases in which total internal refection is possible from either the top or bottom surface of a layer, determine the amount by which the angle of incidence exceeds the critical angle.
A 95 kg man standing on a surface of negligible friction shoves a 75 g stone lying at his feet, giving it a velocity of 4.0 m/s. What velocity does the man obtain accordingly.
The electric potential at a position located a distance of 18.6 mm from a positive point charge of 7.50×10-9C and 14.8 mm from a second point charge is 1.10 kV
The centripetal and tangential accelerations are equal
A golfer takes two putts to get his ball into the hole once he is on green. The first putt displaces the ball into the ball 6.7 m east, and the second 2.16 m south. What displacement would have been needed to get the ball into the hole on first putt.
A chair of weight 135 lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of = 38 directed at an angle of 42 below the horizontal and the chair slides along the floor.
An intergalactic rock star bangs his drum every 1.70s. A person on earth measures that the time between beats is 2.5s. How fast is the rock star moving relative to earth.
