Answer 1

Answer:

sry don't know.. thank you for free points

Answer 2

Explanation:

Net acceleration is the resultant acceleration of centripetal acceleration and tangential acceleration thus find both of them as follows:

Ac− be centripetal acceleration.

At− be tangential acceleration 

Anet=(Ac2+At2)

Now then,

Ac is RV2=1025=2.5m/s2

At is given as 2.m/s2, thus 

Anet=(2.52+22)

         =3.20m/s2.
