Answer:
<u>Given</u><u> </u><u>-</u>
- Initial Velocity, u = 114 m/s
- Final velocity, v = 77 m/s.
- Time taken, t = 9 sec.
<u>To</u><u> </u><u>find</u><u> </u><u>-</u><u> </u>
<u>Solu</u><u>tion</u><u> </u><u>-</u>
Here, using the equation of motion v = u + at we can find the acceleration easily.
★ Here,
- V = Final velocity
- U = Initial Velocity
- A = Acceleration
- T = Time.
<u>Subs</u><u>tituting</u><u> </u><u>the</u><u> </u><u>values</u><u> </u><u>-</u>
→ 77 = 114 + a(9)
→ 9a = 114 - 77
→ 9a = 37
→ a = 37/9
→ a = 4.1 m/s

The force of gravity between two objects is increased when the mass of objects is increased.
Answer:
Explanation:
Given that,
Mass of first car
M1= 328kg
The car is moving in positive direction of x axis with velocity
U1 = 19.1m/s
Velocity of second car
U2 = 13m/s, in the same direction as the first car..
Mass of second car
M2 = 790kg
Velocity of second car after collision
V2 = 15.1 m/s
Velocity of first car after collision
V1 =?
This is an elastic collision,
And using the conservation of momentum principle
Momentum before collision is equal to momentum after collision
P(before) = P(after)
M1•U1 + M2•U2 = M1•V1 + M2•V2
328 × 19.1 + 790 × 13 = 328 × V1 + 790 × 15.1
16534.8 = 328•V1 + 11929
328•V1 = 16534.8—11929
328•V1 = 4605.8
V1 = 4605.8/328
V1 = 14.04 m/s
The velocity of the first car after collision is 14.04 m/s
