A projectile is launched 3.0 meters above the ground. The initial velocity of the projectile is vi and can vary between 15.0 m/s - 75.0 m/s with an initial angle of θi that can vary between 10.0o - 80.0o. You are free to choose any values between these ranges. Clearly indicate your value for vi and θi. a) What is the maximum height of the projectile? b) How long is the projectile in the air? c) How far from the launch does the projectile land? d) The initial angle is changed to 90o. How long before the projectile reaches the ground? e) The projectile mass is doubled. By how much does the range increase?

A projectile is launched upward with an initial velocity of 25 m/s at an angle of 53 degrees above the horizontal. How far will the projectile travel horizontally before it reaches the same height it was launched from? How long will the projectile be in the air if it is launched from a height of 32 meters above flat ground? The answers are 60m and 5.2s. Can you please show how to get to that?

A streamlined and compact projectile is launched from flat ground on a valley toward a distant hillside at an Army testing ground in Nevada. The projectile’s initial speed is vi = 150. m/s as it leaves the cannon. The initial angle of launch θi of the projectile is unknown. The projectile makes impact high on the distant hill a time t = 3.00 s after its departure. From GPS sensors we know that the site of impact is a straight-line...

A 4.0 kg projectile is launched into the air with an initial velocity of 15 m/s at an angle of 30° above the horizontal. When the projectile reaches its maximum height it explodes, splitting in two parts, one of mass 3.0 kg and one of mass 1.0 kg. Assume the explosion was essentially instantaneous. Determine the maximum height of the projectile using energy. After the explosion, if the 1.0 kg mass is moving at 1/2 the speed it was right...
