Gravitational Force

Physics
1 answer:
Ipatiy [6.2K]3 years ago
5 0

Explanation:

Gravitational force

The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself.

Normal force

The normal force is the support force exerted upon an object that is in contact with another stable object.

Friction force

The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it.

Tension force

The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends.

Spring force

The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it.

A ball is droped from a height of 16m how much time will pass before the ball hits the ground​
sergey [27]

Answer:

The time is 1.8s

Explanation:

The ball droped, will freely fall under gravity.

Hence we use free fall formula to calculate the time by the ball to hit the ground

h= \frac{1}{2}g{t}^{2}

Where h is the height from which the ball is droped, g is the acceleration due to gravity that acted on the ball, and t is the time taken by the ball to hit the ground.

From the question,

h=16m

Also, let take

g = 9.8m{s}^{-2}

By substitution we obtain,

16= \frac{1}{2}\times 9.8{t}^{2}

\implies32=9.8{t}^{2}

Diving through by 9.8

\frac{32}{9.8}= \frac{ 9.8{t}^{2} }{9.8}

\implies{t}^{2} =3.265

square root both sides, we obtain

\implies t= \sqrt{3.265}

t=1.8s

lisov135 [29]

Answer:

Explanation:

v² = u² + 2as

v² = 17² + 2(-9.8)(-51)

v² = 1,288.6

v = ±35.89707...

v = 36 m/s
