An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.50 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 35.0 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target?
A projectile is fired with an initial speed of 65.9 m/s at an angle of 37.8 degree above the horizontal on a long flat firing range. Determine the total horizontal distance covered (that is, the range)
A 59kg woman trips while walking down the street. She stumbles forward and falls onto her outstretched right hand. At the instant her hand contacts the ground her whole body is moving downward at a velocity of 9m/s and has a downward acceleration ..
The head of a grass string trimmer has 100 g of cord wound in a light, cylindrical spool with inside diameter 3.00 cm and outside diameter 18.0 cm as shown in the figure below. The cord has a linear density of 10.0 g/m. A single strand of the cord..
