Lena and Mei dive from an overhang into the lake below. Mei simply drops straight down from the edge, but Lena takes a running start and makes a dashing jump with an initial horizontal velocity of 25 m/s. Neither person experiences any significant significant air resistance. Who reaches the lake below first? Lena and Mei reach the lake at the same time. Lena reaches the lake first. Mei reaches the lake first. It is impossible to know without knowing their masses.

Abby and Lola dive from an overhang into the lake below.Abby simply drops straight down from the edge, but Lola takes a running start and jumps with an initial horizontal velocity of 25 m/s.Neither person experiences any significant air resistance.Compare the time it takes each of them to reach the lake below.Group of answer choicesAbby and Lola will reach the surface of the lake at the same time.Lola reaches the surface of the lake first.Abby reaches the surface of the lake first.There is not enough information to determine.

Abby and Lola dive from an overhang into the lake below.Abby simply drops straight down from the edge, but Lola takes a running start and jumps with an initial horizontal velocity of 25 m/s.Neither person experiences any significant air resistance.Just as they reach the lake belowGroup of answer choicesthe speed of Abby will always be 25 m/s larger than that of Lola.the speed of Abby is larger than that of Lola.they will both have the same speed.none of thesethe speed of Lola will always be 9.8 m/s larger than that of Abby.

Shin and Hana are having fun at a water park. They travel down the slides as shown above (with a somewhat vague representation of them), each of which start a distance h above the water. Who has the faster speed when reaching the bottom of the slide? It's impossible to know, since we don't know the exact curvature of each slide. They both have the same speed at the bottom. Hana Shin

Jamieson is competing in his school’s 3.0-metre diving competition. For his last dive, he is performing a forward somersault. The duration of the dive must be exactly 1.75 seconds or he will under- or over-rotate before hitting the water. He jumps upwards off the board with a vertical velocity of 6.0 m s−1 and takes $t$t​ seconds to land in the pool. Take the upwards direction as positive.Which of the following correctly describes the initial velocity during the jump?A0 m s−1B6.0 m s−1C−6.0 m s−1D6.0 m s−2

Gayle runs at a speed of 3.70 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 45.0 kg, the sled has a mass of 5.15 kg and her brother has a mass of 30.0 kg.
