Question

Can someone help me with Q1 And Q2 please !!!!

Answer 1

Answer:

Q1.acceleration=3u/20

Q2.a=13.908m/s

b.50.069km/hr

Step-by-step explanation:

Q1.V=U+at

1. u=um/s
2. v=4um/s
3. t=20s

v=u+at

substituting we have a=3u/20m/s^2 in terms of u

Q2.velocity =distance/time

v=100/7.19=13.908m/s
