i think that it is 50 because if u multiply you will get 50.

F = ma. Thus, acceleration is the force divided by the mass. Here, 10/2 = 5ms-2.
KE = 1/2mV^2 KE = 1/2(50kg)(2m/s)^2 = 100 Joules

4m/s Acceleration = velocity change / time = (9m/s - 5m/s) / 4 sec A = (9-5) / 4 = 1 m/s2.
F = ma. Thus, acceleration is the force divided by the mass. Here, 10/2 = 5ms-2.
Force=mass*acceleration -> (70 kg)*(5m/s^2)=350 kg m/s^2 OR 350 N (newtons)
Mission
While typing there is no provision to raise -2 as the power of s ie s-2 So it has been just typed as ms-2. m s-2 read as metre per second sqare. This is the unit for acceleration. So 5 ms-2 is the acceleration on a moving body.
Use Pythagoras' Theorem to find its value. For example, if it was moving at 3ms-1 in the x direction and 4ms-1 in the y direction, its absolute velocity would be the square root of (9+16), 5ms-1.
2ms lower faster
The average acceleration is (Vfinal minus Vinitial) divided by (time). Since Vinitial=zero, this is just 25/5 = 5ms-2 (meters per second per second). That number is a little bit more than 1/2 the acceleration of gravity.
