Question

please help









.......????​

Answer 1

Explanation:

initial velocity 0

final velocity 15

time 2 s

a=v-u/t

a=7.5

2as=v-u(square)

14s=225

s=225/14

2. force =ma

v=15

u-0

t-2

a=15/2=7.5

f=7.5×1500

11259N

Answer 2

Answer: a. here distance = velocity × time

VELOCITY = 15 M/S

TIME = 2 S

=> 15 × 2

=> 30m

b. F = ma

F = M × (V-U/T)  

M = 1500 KG                                                ∵ A = V-U/T

A = 15-0/2

A = 7.5 M/S²

F = 1500 × 7.5

F = 11250 N
