Question

The position x, in meters, of an object is given by the equation x =A + Bt + Ct^2, where t represents time in seconds. What are the SI units of A. B, and C? 10) What is the sum of 1.53 + 2.786 + 3.3 written with the correct number of significant figures? Convert.. speed of 4.50 km/h to units of ft/min. (1.00 m - 3 28 ft) Find the polar coordinate r for a point located at the Cartesian coordinates (x y) = (2.50m, 1.80m). 5 Find the polar coordinate theta for a point, located at the Cartesian coordinates (x,. y) = (2.50 m. 1.80m).

Explanation / Answer

1. x = A + Bt + Ct^2

so unit of A, Bt and Ct^2 will be m.

so A = m

B = m/s and C = m/s^2

Ans(d)

2. 1.53 + 2.786 + 3.3 = 7.616

3. 4.50 km/ hr = 4.50 x (1000 x 3.28 ft) / 60 min = 246 ft/min

(d)

4. r = sqrt(x^2 + y^2) = sqrt(2.50^2 + 1.80^2) = 3.08

(a)

5. theta = tan^-1(1.80 / 2.50) = 35.8 deg

(b)
