Curiosity, the Mars rover designed to explore Gale Crate has a maximum speed of 0.14 km/h. If the rover was moving at this speed on a flat Martiansurface and hit a small bump that projected it off the surface at an angle of 28°, how long would it be “airborne” on Mars given that the acceleration due to gravity on Mars is 3.711 m/s²?
On a planet very similar to Earth, but slightly denser, where acceleration due to gravity is 10 m/s2, a projectile is fire vertically from a height of 100 meters with an initial velocity of 40 m/s. Its position above the ground after t seconds is given by h(t) = 100 + 40t − 5t2 meters.find the velocity of the projectile as it hits the ground
An astronaut on a distant planet kicks a soccer ball at an angle of 45.1 degrees above horizontal, with an initial speed of 11.5 m/s. The ball is kicked over flat ground, and the acceleration due to gravity on the planet is 2.87 m/s2. The planet has no atmosphere. How far horizontally does the ball travel, in meters, while it is in flight?
On the moon the acceleration due to gravity is 1/6 of Earth's. A ball is thrown straight up to the moon and it takes t= 19s to return to the surface. What is the numeric value for the magnitude of the free fall acceleration on the moon, g in m/s^2? Write an expression for the maximum height achieved by the ball on the moon, hm, in terms of the gravitation acceleration on earth, g, and the time, t. What is the numeric value for this height in meters? What is the difference in the maximum height of the ball when it is theon on the Moon (hm) and the ball being thrown on the Earth (hE), assuming the same time of flight?

During the time it takes the car to travel 102 degrees around, what is the magnitude of the car s average acceleration? 13.96 m/s^2 6.98 m/s^2 12.19 m/s^2 0 m/s^2
Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what Initial velocity would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7m/s2 .
Does a car moving around a circular track with constant speed have (a) zero acceleration, (b) an acceleration in the direction of its velocity, (c) an acceleration directed away from the center of its path, (d) an acceleration directed toward the center of its path, or (e) an acceleration with a direction that cannot be determined from the given information?

A helicopter is ascending vertically with a speed of 5.30 m/s. At a height of 107 m above the Earth, a package is dropped from the helicopter. How much time does it take for the package to reach the ground? [Hint: What is v0 for the package?] Express your answer to three significant figures and include the appropriate units. My Answer is that t= 4.163 but what unit is it? I tried s, m/s, min but none of them were correct. PLEASE HELP CONFIRM MY ANSWER and THE UNIT along with 4.163
In 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.)
