Question

4. In the comics and movies, the Incredible Hulk often travels great distances by making huge leaps. According to Marvel.com, the Hulk is capable of leaping a horizontal distance of up to three miles (4.28 km) in a single leap.

a. What initial angle should the hulk jump at if he wants to maximize his horizontal distance?

b. What initial velocity must the Hulk jump with if he is going to reach a horizontal distance of 4.28 km.

c. What is the maximum height reached by the hulk during this jump.

d. When Hulk is at the maximum height, what is the magnitude and direction of his velocity?

The inventory consist of

Xo - x initial

X - x final

Vo - velocity initial

V - velocity final

a - accelerate

t - time

Answer 1

Horizontal Range,

For a given initial velocity u ,we get maximum range when is maximum

Max value of is 1

(a)ANSWER:

We get max range when projectile is launched at 45 deg.

==============

(b)Given R =4.28km

ANSWER:

================

(c)Use formula

ANSWER:

==================

(d)

When Hulk is at max height , vertical velocity becomes zero

Since there is no acceleration in horizontal direction, horizontal velocity remains same

ANSWER:

Direction

Horizontal velocity is along x axis

ANSWER:

===============
