can someone answer these please?

1. If a NERF dart is fired from a NERF gun vertically with an initial speed of 10.0 m/s and the only acceleration that acts is gravity, what is the maximum height it achieves? Round to one decimal place.

2. What is the total time of flight of the dart from the previous problem? Round to two decimals

A ball is thrown vertically upwards with an initial velocity of 10 m/s, from a platform that is at a height of 75 m above the ground. The ball reaches a maximum height and, on the way down, misses the platform and falls all the way to the ground. Take the magnitude of the acceleration due to gravity to be 10 m/s2. (a) What is the velocity of the ball just before it reaches the ground? (b) How many seconds...

An object is thrown vertically upward from the surface of Mars, where the acceleration due to gravity is ?1=3.70 m/s2.g1=3.70 m/s2. The initial velocity is ?1,v1, and the object reaches a maximum height of ?1.y1. What is the maximum height, ?2,y2, if the object is thrown with a speed of ?2=1.15?1v2=1.15v1 from the surface of Saturn's moon Rhea? The acceleration due to gravity on Rhea is ?2=0.264 m/s2.g2=0.264 m/s2. Give your answer as a multiple of ?1.

A projectile is fired (by remote actuator) from a large flywheel supported on its axle by a stand of height h=25m. The flywheel has radius R= 20m; it spins with a period of revolution p=5s. Adam decides to release a ball at the very top of the rotation, so that its velocity is horizontal. What is the initial speed v of the ball, just as Adam releases it? How long is the ball in flight? When the ball lands, how...
