Question

body of mass 1200 kg is at rest. Calculate the force required to it parts of velocity of 20m/s in 10 seconds.​

Answer 1

Answer:

2400N

Explanation:

Acceleration= v/t

=20/10=2m/s²

Now F= ma

= 1200× 2= 2400N= force

Answer 2

Answer:

given, mass = 1200 kg

final velocity needed (v) = 20 m / s

time taken = 10 s

initial velocity ( u) = 0

thus, acceleration needed = v - u /t

= 20 - 0 /10

= 2 m/s^2

force needed = mass * acceleration

= 1200 * 2 = 2400N
