Given:

v₀ = 10 m/s

v = 0 m/s

a = -2 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (10 m/s)² + 2 (-2 m/s²) Δx

Δx = 25 m

Estimate the volume of each ball. Use the formula

Mila [183]

The given question is incomplete. The complete question is:

Estimate the volume of each ball. Use the formula $v=\frac{4\pi\times r^3}{3}$ where v is the volume and r is the radius. record the volume in table A of your student guide. The radius of the tennis ball is 2.1 cm and the radius of thr golf ball is 2.0 cm. What is the estimated volume of the table tennis ball in $cm^3
$ What is the estimated volume of the golf ball in

Answer: Volume of the tennis ball is $38.8cm^3$ and Volume of the golf ball is $33.5cm^3$

Explanation:

We have to find the Volume of tennis ball and golf ball by using the formula $v=\frac{4\pi\times r^3}{3}$

Radius of the tennis ball = 2.1 cm

Radius of the golf ball =2.0 cm.

Putting the value of radius in the formula , we get:

Volume of the tennis ball = $\frac{4\times 3.14\times (2.1cm)^3}{3}
=38.8cm^3$

Volume of the golf ball = $\frac{4\times 3.14\times (2.0cm)^3}{3}
=33.5cm^3$

Volume of the tennis ball is $38.8cm^3$ and Volume of the golf ball is $33.5cm^3$
