A golf ball reaches a height of 150 m before it stops rising and starts to fall to the ground. What is the golf balls speed (rou

artcher [175]

Answer:

v = 54 m/s

Explanation:

Given,

The maximum height of the flight of golf ball, h = 150 m

The velocity at height h, u = 0

The velocity of the golf ball right before it hits the ground, v = ?

Using the III equations of motion

v² = u² + 2gh

Substituting the given values in the above equation,

v² = 0 + 2 x 9.8 x 150 m

= 2940

v = 54 m/s

Hence, the speed of the golf ball right before it hits the ground, v = 54 m/s

If two proton approach each other with speed of 400m\s and 450m\s respectively what is the total momentum of the two particle sy

lilavasa [31]

Answer: $83.65\times 10^{-27}\ kg.m/s$

Explanation:

Given

The velocities of the protons are 400 m/s and 450 m/s

Mass of the Proton is $m=1.673\times 10^{-27}\ kg$

Since they travel in the opposite direction, therefore, their momentum cancels out each other.

Momentum is the product of mass and velocity

$\therefore m(450-400)\\\Rightarrow 1.673\times 10^{-27}\times 50\\\Rightarrow 83.65\times 10^{-27}\ kg.m/s$

The direction of momentum is in the direction of proton having 450 m/s velocity.
