john throws .4 kg ball with velocity of 18 m/s. Hits .2 kg bottle and bottle flies 25 m/s. How fast is ball traveling after hitt
UNO [17]

Answer:

5.5 m/s

Explanation:

Assuming the bottle is initially stationary, we can write the law of conservation of momentum as follows:

p_i = p_f\\m_b u_b = m_b v_b + m_B v_B

where

m_b = 0.4 kg is the mass of the ball

u_b = 18 m/s is the initial velocity of the ball

m_B = 0.2 kg is the mass of the bottle

v_B = 25 m/s is the final velocity of the bottle

v_b is the final velocity of the ball

Solving for v_b,

v_b = \frac{m_b u_b - m_B v_B}{m_b}=\frac{(0.4 kg)(18 m/s)-(0.2 kg)(25 m/s)}{0.4 kg}=5.5 m/s

A mass of 790 kg is hanging from a crane (neglect the mass of the cable and the hook). While the mass is being lowered, it is sp
Margarita [4]

Answer:

Explanation:

Given

mass of object hanging from crane is m=790\ kg

mass is speeding up with a=2.7\ m/s^2

If T is the Tension in the cable then

mg-T=ma

T=mg-ma

T=m(g-a)

T=790\times (9.8-2.7)

T=790\times 7.1

T=5609\ N
