A rescue pilot drops a survival kit while her plane is flying at an altitude of 1.5 km with a forward velocity of 100.0 m/s. If
tresset_1 [31]

1750 meters.  
First, determine how long it takes for the kit to hit the ground. Distance over constant acceleration is: 
d = 1/2 A T^2
 where
 d = distance
 A = acceleration
 T = time 
 Solving for T, gives
 d = 1/2 A T^2
 2d = A T^2
 2d/A = T^2
 sqrt(2d/A) = T 
 Substitute the known values and calculate.
 sqrt(2d/A) = T
 sqrt(2* 1500m / 9.8 m/s^2) = T
 sqrt(3000m / 9.8 m/s^2) = T
 sqrt(306.122449 s^2) = T
 17.49635531 s = T 
 Rounding to 4 significant figures gives 17.50 seconds. Since it will take
17.50 seconds for the kit to hit the ground, the kit needs to be dropped 17.50
seconds before the plane goes overhead. So just simply multiply by the velocity. 
17.50 s * 100 m/s = 1750 m

A ball is thrown horizontally at a speed of 24 meters per second from the top of a cliff. if the ball hits the ground 4.0 second
Viktor [21]

Answer:

78.4 m

Explanation:

To obtain the height of the cliff;

We can use the Relation to obtain the final velocity, v

v = u + at

a = acceleration due to gravity = 9.8m/s²

v = 0 + (9.8*4)

v = 0 + 39.2

v = 39.2 m/s

To obtain the Height, S

v² = u² + 2aS

39.2^2 = 0 + 2(9.8)S

39.2^2 = 0 + 19.6S

1536.64 = 19.6S

S = 1536.64 / 19.6

S = 78.4 m
