105 kg m/s
Explanation:
The change in momentum of the car is equal to the impulse, which is equal to the product between the force applied and the time of the collision:
in this case, the force applied is F=60.0 N, while the time of the collision is 
, so the change in momentum of the car is
Explanation:As always, if the relation does not come to mind immediately, take a glance at the basic kinematic equations of constant acceleration
what do we know? Vi start speed; Vf terminal speed; acceleration a; and we want to know time t. Three of the relations have a term in d distance - which we don’’t know. That leaves this one: Vt = Vi + a*t. Here we go then:
44 = 0 + 5 * t so t = 44 / 5 = 8.8 hours
Answer:
The quantitative relationship between heat transfer and temperature change contains all three factors: Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.

The solved problem is in the photo. Hope it helps.
Answer:
33.5
Explanation:
The given expression is;
2134211 - 12431 - 24143x = 1312431
To solve this problem, simplify the similar terms;
2121780 - 24143x = 1312431
- 24143x = 1312431 - 2121780
- 24143x = -809349
divide both sides of the expression by -24143;
x = 33.5
