A wheel starts from rest and rotates with constant angular acceleration and reaches an anaular speed of 12 rad/s in 3 s. Find (a

Vadim26 [7]

Answer:

(a) 4 rad/s^2

(b) 18 rad

Explanation:

w0 = 0, w = 12 rad/s, t = 3 s

(a) Let α be the angular acceleration.

w = w0 + α t

12 = 0 + 3 α

α = 4 rad/s^2

(b) Let θ be the angle rotated

θ = w0 t + 1/2 α t^2

θ = 0 + 0.5 x 4 x 9

θ = 18 rad

Covert 60 mph to SI mks units

Flauer [41]

26.82m/s

Explanation:

Given:

speed = 60mph

problem: convert to m/s

To solve this problem, we have to find the right and appropriate conversion factor which equals to 1 to multiply this unit with:

we are converting:

miles to meters

hours to seconds

1.609km = 1mile

1000m = 1km

60s = 1 min

60 min = 1hr

Now to convert from mph to m/s

60 x $\frac{mi}{hr}$ x $\frac{1.609km}{1mi} x \frac{1000m}{1km} x \frac{1hr}{60min} x \frac{1m}{60s}$

= 26.82m/s
