Calculate the horizontal projectile range with the cannon elevated 6m above the x-axis, with an initial speed of 14 m/s and an i

Paul [167]

Answer:

d = 20.25 m

Explanation:

h = 6m, V = 14 m/s, θ=14°

⇒ Vx=V × Cosθ=13.58 m/s and Vy = V × Sinθ=3.39 m/s

to find time t by h=-Vy t + 1/2 g t² (after putting value and simplifying) (-ve for downward motion)

4.9 t² - 3.39 t - 6 =0

⇒ t=1.5 sec (ignoring -ve root)

Now Vx = d/t

13.5 m/s = d / 1.5 s ⇒ d = 20.25 m

A penny is dropped from the top of a building 290 m high. Ignoring air resistance, if

Kryger [21]

Answer:

1. Velocity = 75.39 m/s

2. Air resistance

3. Mass of the coin

Explanation:

1. Given that the height of the building is 290 m. From Newton's third law of motion,

$V^{2}$ = $U^{2}$ + 2gh

where: V is the final velocity of the coin, U is the initial velocity, g is the force of gravity and h is the height.

Since the coin was dropped from a height, its initial velocity is zero. The force of gravity is taken as 9.8 m/ $s^{2}$ , so that:

$V^{2}$ = 0 + 2 x 9.8 x 290

= 5684

V = $\sqrt{5684}$

= 75.3923

The velocity with which the coin hits the ground is 75.39 m/s.

2. Air resistance: During the free fall of the coin, the direction of wind flow could either cause an increase or decrease the value predicted.

ii. Mass of the coin: This can also affect the predicted value.
