Like a then it would be A something I guess it goes like that
Let the salmon jump with speed v at an angle of 33.3 degree
So here we can find out the components of his velocity in x and y direction
now the horizontal displacement of the salmon is 3.15 m so he cover this horizontal distance with constant speed as there is no acceleration in x direction
here we can say
now in Y direction it is an accelerated motion as it is accelerated due to gravity
now we will plug in v*t = 3.76
now speed v is given by equation above
so here he must have to jump with minimum speed of 5.25 m/s
Answer:
False
Explanation:
The depending on what type of pressure is enclosed in a object, the smaller the object the more pressure because that pressure has limited room to escape.
Answer:
212.5 N/m
Explanation:
Work, W = 1700 J
y1 = 2 m
y2 = 6 m
y = y2 - y1 = 6 - 2 = 4 m
Let K be the spring constant.
Work done is given by
W = 1/2 Ky²
1700 = 0.5 x K x 4 x 4
K = 212.5 N/m
Thus, the spring constant is given by 212.5 N/m.
Answer:
<h2>
1.621 kg</h2>
Explanation:
1.324 kg and 297 g.
First convert 297 g to kg
Now add them up
