The record distance in the sport of throwing cowpats is 81.1 m. This record toss was set by Steve Urner of the United States in

N76 [4]

Answer:

28.2 m/s

Explanation:

The range of a projectile launched from the ground is given by:

$d=\frac{v^2}{g}sin 2\theta$

where

v is the initial speed

g = 9.8 m/s^2 is the acceleration of gravity

$\theta$ is the angle at which the projectile is thrown

In this problem we have

d = 81.1 m is the range

$\theta=45^{\circ}$ is the angle

Solving for v, we find the speed of the projectile:

$v=\sqrt{\frac{dg}{sin 2 \theta}}=\sqrt{\frac{(81.1 m)(9.8 m/s^2)}{sin (2\cdot 45^{\circ})}}=28.2 m/s$

How much kinetic energy does a roller coaster have if its mass is 3000 kg and is moving at 30 m/s

Jobisdone [24]

The Kinetic energy of an object is given by:
$E_k= \frac{1}{2}mv^2$

Where m is the mass of the object (kg) and v is the velocity of the object (ms-1)

Substituting in:
$E_k= \frac{1}{2}*3000*30^2 = 1350000J$
Therefore the Kinetic energy of the object is 1.35MJ

A sailboat increases its speed from 1m/s to 4m/s in 3 seconds what will the speed of the sailboat be at 6 seconds if the acceler

Stels [109]

Since 1m/s goes to 4m/s in 3 seconds,
then 4m/s goes to 8m/s in 6 seconds.
So your answer would be:
4m/s to 8m/s in 6 seconds
