Answer 1

Answer:

1. 4N

2. 40 N

3. 2kg

4. 0.5kg

5. 4500N

Explanation:

1. m=2kg

a=2m/s²

F=ma = 2×2 = 4N

2. F =5×8 = 40N

3. F=6N

a=3m/s²

m=F/a=6/3=2kg

4. m=6/12 = 0.5kg

5. u=0, v=30m/s, t=10, m=1500kg

a=(v-u)/t = (30-0)/10 = 3 m/s²

F = ma= 1500×3=4500N

I hope you can solve the remaining problems.
