A ball is thrown vertically upwards with an initial velocity of 22 m/s. When will its speed be 10
gogolik [260]

Answer:

<em>The ball's speed will be 10 m/s at t=1.22 seconds</em>

Step-by-step explanation:

The vertical motion of an object is controlled by the force of gravity. This means that there is a non-zero net force acting on the object that makes it accelerate downwards.

If the object is thrown upwards at speed vo, its speed at time t is:

v_f=v_o-g.t

Where g is the acceleration of gravity g=9.8 m/s^2.

Our ball is thrown upwards with v0=22 m/s. We need to calculate the time when its speed is vf=10 m/s.

Solving the above equation for t:

\displaystyle t=\frac{v_o-v_f}{g}

Substituting:

\displaystyle t=\frac{22-10}{9.8}=\frac{12}{9.8}

t=1.22 seconds

The ball's speed will be 10 m/s at t=1.22 seconds

What is the derivative of g(x)=e^(x^2+2x)+3x
UNO [17]
Ok first we can split it in two : e^{x^2+2x} and 3x.

The derivative of 3x is 3.

For the first part, we use the chain rule : [f(g(x))]'=g'(x)f'(g(x)) hence (e^{x^2+2x})'=(x^2+2x)'e^{x^2+2x} (since the derivative of the exponential is itself) hence g'(x)=(2x+2)e^{x^2+2x}+3
