Question

A cheetan starts from ,rest , and accelerates at 2m /s 2 for 10 seconds calculate 1) the final velocity 2) the distance travelled​

Answer 1

Answer:

Initial velocity, u=0 m/s

Final velocity, v=?

Acceleration, a=2m/s

2

Time, t=10s

(a) Using, v=u+at

v=0+2×10=20m/s

(b) Distance travelled is:

s=ut+
