Question

A powerful motorcycle can accelerate from rest to 30m/s in 6s. (a) What is its average
acceleration? (b) How far does it travel in that time?​

Answer 1

Answer:

60m/s in 12second... I hope this is the answer

Answer 2

Answer:

initial velocity = 0

final velocity = 30m/s

time given = 6 sec.

a) Avg. acceleration = change in velocity/ time

=> (30 - 0)/6 = 5m/s2

b) distance travelled in 6 sec.

S = ut + 1/2 at2

= 0*6 + 1/2 * 5 * 6 * 6

= 90 m.

a) 5m/s2 b) 90m
