Answer:

60m (to nearest meter)

Explanation: How far the ball traveled refers to the range covered by the ball before it hits the ground. For an object projected at an angle of ∝ to the horizontal, the range, R covered is given by;

R=u^{2}sin2\alpha/2g

Where u is the initial velocity and g is acceleration due to gravity.

u=26mls\\\alpha=30^{o}\\g=9.81m/s^{2}

The value of g could be safely assumed to be 9.8m/s^{2}

Therefore;

R=26^{2}sin2(30)/9.8

R=(26*26*sin60)/9.8

R=676*0.8660/9.8

R=59.68m which is approximately 60m to nearest meter.

al aplicar una fuerza de 2 N sobre un muelle este se alarga 4cm.¿cuanto se alargara si la fuerza es el triple?¿que fuerza tendri

1) 12 cm

2) 3 N

Explanation:

1)

The relationship between force and elongation in a spring is given by Hooke's law:

F=kx

where

F is the force applied

k is the spring constant

x is the elongation

For the spring in this problem, at the beginning we have:

F=2 N

x=4 cm

So the spring constant is

k=\frac{F}{x}=\frac{2N}{4 cm}=0.5 N/cm

Later, the force is tripled, so the new force is

F'=3F=3(2)=6 N

Therefore, the new elongation is

x'=\frac{F'}{k}=\frac{6}{0.5}=12 cm

2)

In this second problem, we know that the elongation of the spring now is

x=6 cm

From part a), we know that the spring constant is

k=0.5 N/cm

Therefore, we can use the following equation to find the force:

F=kx

And substituting k and x, we find:

F=(0.5)(6)=3 N

So, the force to produce an elongation of 6 cm must be 3 N.

A hunter stood at about 60 m away from a tree. He used the bow to release the arrow in order to shoot a coconut held by a monkey
Marianna [84]

Answer:

Time taken to reach the tree

they have given the maximum height which is 25m

therefore...

v=u+at (upward)

0 = 45sin(20)-9.81t

t = 1.56s

No because it’s too much different between the real value and measured value
