Explanation:
<u>Projectile Motion</u>
It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
Being vo the initial speed of the object, θ the initial launch angle, and the acceleration of gravity, then the maximum horizontal distance traveled by the object (also called Range) is:
The projectile was launched at an angle of θ=30° with an initial speed vo=20 m/s. Calculating the range:
The range is 35.35 m
Answer: 2.63 m/s
Explanation:
The question in english is written below:
During an attemp of croquet game, a 0.52 kg ball at rest on the grass is hit by a mallet with an average force of 190 N, if the mallet is in contact with the ball for , Whay is the speed of the ball just after being hit?
According to Newton's second law of motion, the force exerted on an object is directly proportional to its mass
and acceleration
:
(1)
On the other hand, acceleration is defined as the variation of velocity in time
:
(2)
Substituting (2) in (1):
(3)
Where:
Isolating the velocity from (3):
(4)
Finally:
