Question 7 (1 points) A car drives straight off a flat cliff that is 57 m high (its initial velocity is purely horizontal). The point of impact is 130 m from the base of the cliff. How fast was the car traveling when it went over the cliff? Select the correct answer 4.9 m/s Cannot be determined 2.15 11.2 m/s 38 m/s

Step 1
The car's initial velocity is purely horizontal, so we'll separate the motion into horizontal and vertical components. The key here is to remember that the horizontal velocity remains constant throughout the motion because there's no acceleration in the horizontal Show more…

1, A ball is thrown upward with an initial velocity of 25.0 m/s at time t = 0.0 s, from a roof 50 m above the ground. The ball rises, then falls and strikes the ground. The time when the ball strikes the ground is closest to 4.8 s 8.1 s 10.1 s 9.4 s 7.9 s 6.6 s 2, the driver drives his car at a speed of 20 m/s off a 45m high cliff. The road leading to the cliff is inclined upward at an angle of 30o. What is the car's impact speed at the bottom? 33 m/s 36 m/s 12 m/s 42 m/s 49 m/s 20 m/s

A stone is thrown at an angle of 30° above the horizontal from the top edge of a cliff with an initial speed of 12 m/s. A stop watch measures the stone's trajectory time from top of cliff to bottom to be 4.8 s. What is the height of the cliff? (g = 9.8 m/s² and air resistance is negligible) 140 m 110 m 84 m 29 m
