Answer:
erosion
Explanation:
it carries things from one place to another
Answer:
Displacement in Y direction is 0.434 m
Explanation:
initial velocity of the puck is 2.35 m/s at -22 degree
so here it is given as


final velocity is given as 6.42 m/s at 50 degree
so we have


now displacement in Y direction is given as



It's c/f, in which c is the speed of light (300000 m/s)
Answer:
256.68m
Explanation:
that is the procedure above
Answer:
u = 104.68 m/s
Explanation:
given,
horizontal distance = 150 m
elevation of 12.4 m
angle = 8.6°
horizontal motion = x = u cos θ. t .............(1)
vertical motion =
................(2)
from equation(1) and (2)
..........{3}




u = 104.68 m/s
The initial speed of the ball is u = 104.68 m/s
