Question

a motorcycle can accelerate from the rest to 28 m/s in only 4s what is its acceleration​

Answer 1

Answer:

Hope this helps you

Explanation:

Starting velocity u =0 m/s

End velocity v= 28m/s in time t= 4sec

If accleration = f

v= u+ft , 28= 0+ f × 4 , f = 28/4 = 7 m/s^2

Accleration = 7m/sec^2

If distance travelled =S

S= ut +1/2 ft^2 = 0 × 4+(1/2)7× 4^2 =56 m

Distance travelled in 4 sec = 56 m
