Question

Ryan hits a stationary 0.15 kg ball with a force that lasts for 0.08 s and makes the ball shoot across the ice with a speed of 17 m/s. With what force did Ryan hit the ball?
B
D
32 N
320 N
Cannot solve without acceleration
0.204 N

Answer 1

Answer:

$\huge\boxed{\sf F=31.88 \ N}$

Explanation:

Given Data:

Mass = m = 0.15 kg

Velocity = v = 17 m/s

Time = t = 0.08 s

Required:

Force = ?

Formula:

$\displaystyle F=\frac{mv}{t}$

Solution:

$\displaystyle F=\frac{(0.15)(17)}{0.08} \\\\F=\frac{2.55}{0.08} \\\\F=31.88 \ N\\\\\rule[225]{225}{2}$
