Question

Example 21: A constant force of 50 N is applied to a 20 kg block for 10 seconds. (a) what is the final speed of the block if it was originally
moving at a speed of 15 m/s ?
F = 50N
20 kg​

Answer 1

Answer:

40m/s

Explanation:

DATA:

F = 50N

M=20 KG

t= 10s

vi=15m/s

formula

F=ma

50=20 (a)

50÷20=a

2.5m/s^2

formula

vf=vi+at

vf=15+2.5×10

vf=40m/s

Answer 2

Answer:

answer will be vf=

Explanation:

40 m/
