Question

A constant force of 230 N is applied to a 24 kg block of concrete for 25 seconds.

a. What is the final speed of the block if it originally at rest

Answer 1

Explanation:

a = f/m

a = 230/24 = 9.58m/s²

t = 25secs

u = 0m/s

v = ?

a = (v - u)/t

9.58 = (v - 0)/25

9.58 x 25 = v

v = 238.75m/s
