Please show complete work with necessary unit for full credit. Problem 1: A ball is thrown up vertically from the top of a building of height-100 m with an initial speed of 30 m's. It then goes up for a certain period of time and then comes down to the ground. Neglect the air resistance for calculation (a) How high from the ground will the ball go? (b) How long will it take for the ball to reach to the...
A rock takes 3.2 s to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.4 m/s. Calculate the height of the cliff (in meters). Using that information, how long would it take to reach the ground if the rock is thrown straight down with the same speed?
1. A rock is dropped from a bridge that is 15 m above the surface of the river. How long does it take for the rock to hit the water? 2. A ball is thrown upward from the edge of the roof of a 20 m tall building with an initial velocity of 15 m/s. a) What is the maximum height reached by the ball? b) How much time does it take for the ball to reach the ground? c)...
A rock takes 2.40 s to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.17 m/s. How long (in s) would it take to reach the ground if it is thrown straight down with the same speed?
A rock is thrown upward at an initial velocity of 16 ft/sec from a height of 96 feet above ground. How long will it take to hit ground?
will it go? * 31 A rock is dropped from a treetop 19.6 m high, and then, 1.00 s later, a second rock is thrown down. With what initial velocity must the second rock be thrown if it is to reach the ground at the same time as the first?
A rock thrown vertically upward from the surface of the moon at a velocity of24 m/sec reaches a height of s=24t-0.8t^2 meters in t seconds.a) Find the rock’s acceleration and velocity at time t.b) How long does it take the rock to reach its highest point?c) How high does the rock go?d) How long does it take the rock to reach half its maximum height?e) How long is the rock aloft?
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall...

A rock is thrown up from the edge of a tall building. the rock reaches its maximum height 1.os after being thrown. then, when it goes down, the rock hits the ground 9.0s after being thrown. how fast is the rock thrown? what would be the maximum height above the build, which would the rock reach? what is the height of the building?
