When you’re driving a golf ball, a good "follow-through" helps to increase the distance of the drive. A good follow-through mean

Natali [406]

Answer:

$v_{f}$ = F Δt / m

Explanation:

The impulse theorem and momentum is

I = Δp

F Δt = m $v_{f}$ - m v₀

Before touching the ball is without movement, the force is represented by the kinetic energy of the club when it reaches the bottom of the path, so if this force is constant, the time [or the duration of the blow is directly proportional to the speed that the ball acquires.

$v_{f}$ = F Δt / m

The higher this speed, the greater the distance traveled.

Formula one racers speed up much more quickly than normal passenger vehicles, and they also can stop in a much shorter distance.

soldi70 [24.7K]

Answer:

a = -36.8 m/s/s

Explanation:

Initial speed of the car

$v_i = 90 m/s$

finally car will stop after it cover the distance

$d = 110 m$

so we have

$v_f^2 - v_i^2 = 2 a d$

here we have

$0 - 90^2 = 2(a) (110)$

$a = \frac{90^2}{220}$

$a = -36.8 m/s^2$

An opera singer breaks a crystal glass with her voice. Which best explains why this occurs? The pitch of her voice matches the p

aalyn [17]

The frequency at which the body vibrates breaks is natural frequency. The glass with her voice because the frequency of her voice matches the natural frequency of the glass.

<h3>What is the natural frequency?</h3>

When there is no external force acting on the body unless the body vibrates is known as the natural frequency of vibration.it is denoted by $\rm w_n$ .
