Lower body strength is the ability of the body to exert a maximum force against an object external to the body in one maximum effort of the lower body muscles. Gluteals are muscles that make up the buttocks. ... Their roles are to facilitate hip extension and lift the leg to the side.
..... equal to the force from the engine pushing the car forward.
That's why the car is not accelerating. The horizontal forces on it
are balanced.
No Solution:
4x+10y = 40
2x + 5y = 40
2x - 8y=17
x - 4y = 7
One Solution:
2y - X= 12
2y - 2x =10
x + 10y =50
2x + 10y =90
Infinitely Many Solutions:
x + 2y = 1
3x + 6y= 3
2y - 3x = 5
2/5y -3/5x =1
Explanation: You only had 11 equations listed. But I believe these are the ones you want. I took the test and got them right. Hope it helps
Answer:
Speed, u = 29.4 m/s
Explanation:
Given that, A ball thrown straight up climbs for 3.0 sec before falling, t = 3 s
Let u is speed with which the ball is thrown up. When the ball falls, v = 0
Using first equation of motion as :
v = u + at
Here, a = -g
So, u = g × t
u = 29.4 m/s
So, the speed with which the ball was thrown is 29.4 m/s. Hence, this is the required solution.
