Ignoring air resistance:acceleration due to gravity is approx 9.81 m/s²Using Newton's equation of motion:v = u + atwhere:v = final velocity (to find)u = initial velocity = 0 m/s as it was at resta = g - acceleration due to gravity (in a downward direction)t = 8 sv = 0 + g × 8 = 8g (downwards) Taking g as 9.81 m/s² this makes the final velocity v ≈ 8 s × 9.81 m/s² = 78.48 m/s ≈ 78.5 m/s
3 m/s
The solutions are: s = -3/2 and s = -3/2 they have equal roots
14.715 m/s. This is worked out by knowing that gravity will accelerate a body at 9.81 (m/s)/s. The average velocity is the speed at 3s plus the speed at 0s divided by 2. Speed at 0s = 0 x 9.81 = 0 m/s Speed at 3s = 3 x 9.81 = 29.43 m/s (29.43 + 0) / 2 = 14.715 m/s.

MESS
momentum = mass × velocity Assuming they are separate, the total momentum is 200 kg × 0 m/s + 200 kg × 10 m/s = 2000 kg m/s
3 m/s
1,800 kg-m/s
2,000 kg-m/s
2 m/s*heather :)*
Here is a C program that stimulates a simple digital clock: #include #include #include void main() { int h,m,s; h=0; m=0; s=0; while(1) { if(s>59) {m=m+1; s=0; } if(m>59) { h=h+1; m=0; } if(h>11) { h=0; m=0; s=0; } delay(1000); s=s+1; clrscr(); printf("\n DIGITAL CLOCK"); printf("\n HOUR:MINUTE:SECOND"); printf("\n%d:%d:%d",h,m,s); }}
