Question

1. A car travelling at 10ms-accelerates uniformly at 2ms Calculate its velocity after 5s.​

Answer 1

Answer:

Given :-

• A car travelling at 10 m/s accelerates uniformly at 2 m/s².

To Find :-

• What is the velocity after 5 seconds.

Formula Used :-

$\mapsto \sf\boxed{\bold{\pink{v =\: u + at}}}$

where,

• v = Final Velocity
• u = Initial Velocity
• a = Acceleration
• t = Time Taken

Solution :-

Given :

• Initial Velocity (u) = 10 m/s
• Acceleration (a) = 2 m/s²
• Time Taken (t) = 5 seconds

According to the question by using the formula we get,

$\longrightarrow \sf v =\: 10 + 2(5)$

$\longrightarrow \sf v =\: 10 + 2 \times 5$

$\longrightarrow \sf v =\: 10 + 10$

$\longrightarrow \sf\bold{\red{v =\: 20\: m/s}}$

${\small{\bold{\underline{\therefore\: The\: velocity\: is\: 20\: m/s\: .}}}}$

Answer 2

Answer:

20ms-1

Explanation:

as we know

Vf=Vi +at

then

       10+(2)(5)^2

so we get 20ms-2
