Question

On an object of mass 1 kg moving along x-axis with constant speed 8 m/s, a constant forre
2 N is applied in positive y-direction. Find its speed after 4 seconds.
​

Answer 1

Answer:

wait....

Step-by-step explanation:

given : m=1kg

u=8m/s

F= 2N

we HV to find speed after 4s

so using Newton's 2nd laws of motion

F = ma (here putting values of F and m)

2=1a so

a= 2m/s²

now,

using the formula, v =u + at

v=8 + 2*4

=> 8 + 8= 16m/s

so it's speed after 4s is 16m/s.
