Question

A bus starting from rest moves with uniform acceleration of 0.1 metre per second square for 2 minutes find the speed acquired the distance travelled.
​

Answer 1

AnsWer:-

• The speed acquired by the bus is

12m/s.

• The distance travelled by the bus is 720m.

Step-by-step explanation:

Given:-

• Initial speed of the bus = 0m/s
• Acceleration of the bus = 0.1m/s²
• Time taken by the bus = 2 min = 120sec

Need to find:-

• The speed acquired.
• The distance travelled.

Explanation:-

As we know that,

v = u+at

Putting values in this formula,

We get:

v = 0+0.1×120

=> 12m/s

As we know that,

S = it+1/2at²

Putting values in this formula,

We get:

S = (0×120)+1/2×0.1×120²

=> 0+720m

=> 720m

Hence,the speed acquired by the bus is

12m/s and the distance travelled by the bus is 720m.

Answer 2

Answer:

a) 12 meters

b) 720 meters

step by step explanation

intial velocity (u) = 0

final velocity (v) = 0.1m/s

time = 2 minutes ( converted to seconds = 60×2 = 120 seconds )

speed accquried = ?

distance travelled = ?

answer for question A

v=u+at

= 0+0.1×120

= 12metrs

answer for question B

s=ut+1/2at square

= 0 +1/2×0.1(120) square

=720 meters
