Answer:
C. 750 N. left
Explanation:
let the force to the right be positive, and the left be negative
Step one:
given
mass of crate m= 500N
1450N force left
Frictional force of 200 N -----this opposes the motion
500 N opposing force to the right
The net force is equal to the summation of all the forces in Newton
Net force= -1450+200+500
Net force=-750N
The direction is right
Explanation:
Momentum is mass times speed.
p = mv
a) p = (1500 kg) (25.0 m/s) = 37,500 kg m/s
b) p = (40,000 kg) (1.00 m/s) = 40,000 kg m/s
The truck has more linear momentum.
Momentum in the y direction:
pᵧ = (1500 kg) (25.0 m/s) = 37,500 kg m/s
Momentum in the x direction:
pₓ = (1500 kg) (15.0 m/s) = 22,500 kg m/s
Total linear momentum:
p² = pₓ² + pᵧ²
p² = (22,500 kg m/s)² + (37,500 kg m/s)²
p = 43,700 kg m/s
