In a football game, a 96 kg receiver leaps straight up in the air to catch the 0.42 kg ball the quarterback threw to him at a vi

fredd [130]

Answer:

V = 0.074 m/s

Explanation:

given,

mass of the receiver, M = 96 Kg

mass of the ball, m = 0.42 Kg

initial speed of the ball, v = 17 m/s

initial speed of the receiver = 0 m/s

final speed.V = ?

using conservation of momentum

M u + m v = (M + m) V

0 + 0.42 x 17 = (96+0.42) V

96.42 V = 7.14

V = 0.074 m/s

hence, Speed after catching the ball is equal to 0.074 m/s

A wheel is rotating at a rate of 2.0 rev every 3.0s. through what angle, in radian , does the wheel rotate in 1.0s?

igomit [66]

Answer:

$4 \pi$

Explanation:

First of all, let's convert 2.0 rev into radians:

$1.0 rev = 2\pi rad\\2.0 rev = 4 \pi rad$

This means that the angular speed of the wheel is

$\omega = 2.0 rev/s = 4 \pi rad/s$

The angle through which the wheel rotates in a time t is given by

$\theta=\omega t$

And substituting t=1.0 s, we find

$\theta=(4\pi rad/s)(1.0 s)=4 \pi rad$
