Answer:
remain stationary
Explanation:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
When the engine is near the governed RPMand the transmission is in the lower gears, the braking effect of the engine is at its greatest .
It is specified that the legal requirements for the braking system that:
A reasonable distance should be practiced in stopping your vehicle.
Adjournment from the jar or shudder should be smooth and free.
A good braking system’s other necessities are:
Unaffected by heat, water, road grit, dust etc.
Constant continued application while moving downwards from a hill should not decrease its effectiveness and it must have good anti fade characteristics
Adequate durability with economical maintenance and adjustment Its durability must be enough and must have proper adjustment and maintenance.
Answer:
Maximum height reached is given as H = 5.00 m
Explanation:
As we know that if the ball is projected at some angle with the horizontal then the range of the projectile is given by the formula
![R = \frac{v^2 sin2\theta}{g}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7Bv%5E2%20sin2%5Ctheta%7D%7Bg%7D)
here we have
![R = 55 m](https://tex.z-dn.net/?f=R%20%3D%2055%20m)
![\theta = 20^o](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2020%5Eo)
v = 40 m/s
Now we have
![55 = \frac{40^2 sin40}{g}](https://tex.z-dn.net/?f=55%20%3D%20%5Cfrac%7B40%5E2%20sin40%7D%7Bg%7D)
![g = 18.7 m/s^2](https://tex.z-dn.net/?f=g%20%3D%2018.7%20m%2Fs%5E2)
now for maximum height we have
![H = \frac{v^2sin^2\theta}{2g}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7Bv%5E2sin%5E2%5Ctheta%7D%7B2g%7D)
![H = \frac{40^2 sin^220}{2(18.7)}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7B40%5E2%20sin%5E220%7D%7B2%2818.7%29%7D)
![H = 5 m](https://tex.z-dn.net/?f=H%20%3D%205%20m)
lol if not LOVE then its , strongest fundamental force is the strong nuclear force; it is 100 times stronger than the electromagnetic force.
hope this helps:)sorry if it doesnt
Weight is the force acting on a bode weight =mass times gravity
