Question

A boy moving with uniform speed of 2m/s² for five seconds, suddenly accelerates to 3m/s² for 4 seconds. Find a) total distance travelled b) final speed of boy

Answer 1

Answer:

(a) Total Distance = 22 m

(b) Inadequate information

Explanation:

Speed1 = 2 m/s

Speed2 = 3 m/s

Time1 = 5 s

Time2 = 4 s

Distance1 = Speed1 * Time1 = 2*5 m = 10 m

Distance2 = Speed2 * Time2 = 3*4 m = 12 m

Total Distance traveled = (10+12) m = 22 m
