1. A bus starting from rest moves with a uniform acceleration of
0.1 m s2 for 2 minutes. Find (a)
the speed acquired. (b) the
distance travelled.​

Speed acquired (Final velocity) = 12 m/s

Distance travelled = 720 meter

Explanation:

Given:

Uniform acceleration = 0.1 m/s²

Initial velocity = 0 m/s

Time taken = 2 minutes = 2 x 60 = 120 second

Find:

(a)  Speed acquired (Final velocity)

(b) Distance travelled

Computation:

v = u + at

v = 0 + 0.1(120)

Speed acquired (Final velocity) = 12 m/s

Distance travelled = ut + (1/2)(a)(t²)

Distance travelled = (0)(120) + (1/2)(0.1)(120²)

Distance travelled = (1/2)(0.1)(14400)

Distance travelled = 720 meter

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

the independent variable, or the one that is intentionally manipulated is the speed.
