be

(a) 25 m/s. (b) 23 m/s. (c) 18 m/s. (d) 27 m/s​

Answer 1

$\huge\star{\boxed{\underline{\boxed{\boxed{\purple{ANSWER}}}}}}$

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.

Frictional Force: Gravitational Force

Tension Force: Electrical Force

Normal Force: Magnetic Force

Answer 2

18m\s-1 ✅

V = U+AT

step by step

u=8m\s-1

a=2m\s-2

t=5sec

V = U+AT

V = 8m\s-1 + 2m\s-2 * 5sec.

V = 8m\s-1 + 10m\s-1

V = 18m\s-1
