Answer:

**Answer:**

The length is 5.2 mm.

**Explanation:**

**Given that,**

Time period T²= 0.021 s²

Gravity due to acceleration = 9.78 m/s²

**We need to calculate the length **

**Using formula of time period of pendulum**

Where, l = length

g = acceleration due to gravity

T = time period

Put the value into the formula

**Hence, The length is 5.2 mm.**

**Answer:**

a=-2.77 m/s^2

**Explanation:**

Assuming constant acceleration,

v=at + v_0

where v_0 is the initial velocity.

At rest, v=0, so

0=at+v_0

So solving the equation for a:

a=(-v_0)/t

Inserting the numbers yields

a=-2.77 m/s^2

**Answer:u=42.29 m/s**

**Explanation:**

Given

Horizontal distance=167 m

launch angle

Let u be the initial speed of ball

Range

Part a)

Equation of position with time is given as

since this equation is a quadratic equation

so it will be a parabolic graph between t = 0 to t = 1

part b)

at t = 0.45 s

at t = 0.55 s

now the displacement is given as

so the average velocity is given by

part c)

at t = 0.49 s

at t = 0.51 s

now the displacement is given as

so the average velocity is given by
