Question

A car of 300kg moving with an uniform volocity of 20m/s. then the force required to stop the car in 20sec

Answer 1

Hey mate here is your answer....☺☺❤❤


Given ,
mass , m = 300 kg
uniform velocity ,u = 0 m/s
Final velocity, v = 20m/s
time ,t = 20s
a , acceleration =?
a =v-u/t
a = 20-0/20
a = 20/20

$a \: = 1m \div {s}^{2}$

$f \: = m \times a \\ f \: = 300 \times 1 \\ f \: = 300 \: newton$
$i \: am \: not \: sure \:$
