Answer:
I = 1.525 kg.m/s
Explanation:
given,
mass of the ball = 0.165 Kg
height of drop, h = 1.25 m
ball rebound and reach to height, h' = 0.940 m
impulse = ?
using conservation of energy
Potential energy is converted into kinetic energy
v = 4.95 m/s
velocity of the ball after rebound
again using conservation of energy
v' = 4.29 m/s
impulse is equal to change in momentum
I = m ( v' - v )
I = 0.165 x ( 4.29 - (-4.95))
I = 1.525 kg.m/s
It took the train a total of 4 days to travel that long
Answer:
African
Explanation:
The African Institute for Mathematical Sciences (AIMS) is an educational and research institute located in Muizenberg, South Africa. It was founded in 2003. Through the Next Einstein Initiative aims to establish 15 more institutes in the African continent. The founder of AIMS is Neil Turok. AIMS has collaborations with various European Universities.
