Question

plz tell this numerical step by step please i will mark as bra nlist ​

Answer 1

Answer:

1]   ans:  20$m/s^{2}$           if helpful mark me brainliest please.

2]   ans: 8$m/s^{2}$               explanation is given down

Explanation:

v=23m/s

u=15m/s

hence

acceleration=v-u/t

=23-15/4

a=2

Force= mass x acceleration

          =10 x 2

Force=20m/$s^{2}$

by same method you can solve 2nd Q

a=23-15/10

a=0.8

force= 10 x 0.8

force=8$m/s^{2}$
