A ski jumper travels down a slope and leaves the ski track moving in the horizontal direction with a speed of 25 m/s as in Figure. The landing incline below him falls off with a slope of 35°. (a) Where does he land on the incline? (b)Determine how long the ski jumper is airborne, and his vertical component of velocity just before he lands on the slope.

A track meet is held on a planet in a distant solar system. A shot-putter releases a shot at a point 2.0 m above ground level. A stroboscopic plot of the position of the shot is shown in the figure, where the readings are 0.76 s apart and the shot is released at time t = 0. (a) What is the initial velocity of the shot in unit-vector notation? (b) What is the magnitude of the free-fall acceleration on the planet? (c) How long after it is released does the shot reach the ground? (d) If an identical throw of the shot is made on the surface of Earth, how long after it is released does it reach the ground? y (m) 10 5 0 t=0 90 5 10 15 x (m) 20 20 25 30

Doha kicks the ball in a parabolic path. The ball leaves the player’s foot with a speed of 20 m/s, making an angle of 40 o with the horizontal. a) Calculate the maximum height of its trajectory  b) Determine its velocity as it hits the ground again. Air resistance is negligible. c) How far from Darshan does the soccer ball land?

A cart is moving with a constant horizontal velocity of 5.00 m/s. A small pebble is launched from the front of the cart with a velocity of 8.00 m/s at 60.0° above the horizontal as measured relative to the cart (see figure) and experiences no significant air resistance. Cart 60° 8.00 m/s -5.00 m/s Just as the pebble returns to the level from which it was launched, what is its distance from the front of the cart? How far did the pebble travel from its launch point relative to the ground.

The maximum horizontal distance a boy can throw a ball is 50 m. Assume he can throw with the same initial speed at all angles. How high does he throw the ball when he throws it straight upward?

A bullet is fired from ground level at 264 m/s and at an angle of 30.0°. Neglecting air resistance, answer the following questions: (a) What is the initial horizontal component of the velocity? Vix (b) What is the initial vertical component of the velocity? V₁y = (c) How high will the bullet rise? dymax m/s m/s Remember to round your answers to the correct number of significant digits.

A cannonball is launched diagonally with an initial horizontal velocity of 50.0m/s and an initial vertical velocity of 30.0Om/s. Label the hypotenuse, opposite side and adjacent side, and determine all unknowns. initial velocity: m/s initial horizontal velocity: m/s initial vertical velocity: m/s At what angle (0) was the cannonball launched?

jon kicks a soccer ball with an initial horizontal velocity of 15 m/s. Dwight kicks a soccer ball with an initial horizontal velocity of 19 m/s. Whos esoccer ball will have traveled further horizontally after 2 seconds in the air?

An athlete in a long jump trial leaves the ground at an 80o angle and covers a horizontal distance of 8.7 m. The speed with which he can jump remains constant. What should he do to increase the horizontal distance of his jump? Explain why this would work.

Anthony carelessly rolls his toy car off a 79.0-cm-high table. The car strikes the floor at a horizontal distance of 96.0 cm from the edge of the table. (a) What was the velocity with which the car left the table? (Enter the magnitude.)(b) What was the angle of the car's velocity with respect to the floor just before the impact?
