Question

A power motorcycle accelerates from rest to 28m/s in only 4s

Answer 1

Answer:

56 meters

Explanation:

u= om/s

v= 28m/s

t= 4s

v= u+ at

28= 0+4s

4s= 28

Average acceleration = 7m/s square

Displacement = v square + u square + 2as

28 square = 0 square + (2×7s)

784 = 14 s

s= 784/14

s = 56 m

Therefore distance travelled = 56 meters
