+6. K13Q6 - 7. K13Q7 A sports car traveling at 29.5 m/s slows to a velocity of 11.0 m/s over 11.1 s. How far does it move during this time? X Distance 430.08 m Info

Young Hector launches a 200 gram block uphill on a frictionless ramp which is tilted at 30 degrees with the horizontal, as shown in the Figure. At the instant of its launch, the block is moving uphill at 4.00 m/s. Hector observes as the block travels a distance of 50.0 cm uphill on the ramp. In the following, consider the period of time during which the block moves uphill through the 50.0 cm distance shown in the Figure. For simplicity, assume that g = 9.80 m/2. d (50.0 cm) 4.00 m/s h 30°

Twila throws a ball directly downward from a window that is 25.0 m above the ground. It takes the ball 1.97 s to impact with the ground. a) Calculate the initial velocity that the ball was thrown at. b) Calculate the impact velocity. c) If the ball was dropped from rest how long would it have taken to impact the ground?
