what force must act on a 70.0 kg mass to give an acceleration of 0.30 m/s2? find f (use question no.1 formula)
what force must act on a 75.0 kg mass to give to an acceleration of 1.2 m/s2 find the f (USe F=ma as your formula)
nneglecting friction, determine the horizontal force needed to accelerate a 50 kg grocery cart from the rest velocity of 0.85 m/s in 2.45s find a ) fx and b computing for a
PLEASE ANSWER THANK YOU VERY MUCHH!!

Answer:
f = (70.0)(0.30)
f = 21 N
2. f = ma
f = (75.0)(1.2)
f = 90 N
3. *find acceleration first*
a = v/t
a = 0.85/2.45
a = 0.35 m/s^2
f = ma
f = (50)(0.35)
f = 17.5 N
