A motorcycle is capable of accelerating at 5.1 m/s starting feom rest how far can it travel im 1.5 seconds
saul85 [17]

5.1 m/ s


~Multiply 1.5 on both sides since you’re trying to finding out how far it can travel in 1.5 seconds


5.1 x 1.5= 7.65

s x 1.5= 1.5


So a motorcycle can travel 7.65 m in 1.5 seconds.

A basketball with mass of 0.8 kg is moving to the right with velocity 6 m/s and hits a volleyball with mass of 0.6 kg that stays
IceJOKER [234]

Answer:

26.67 m/s

Explanation:

From the law of conservation of linear momentum, the initial sum of momentum equals the final sum.

p=mv where p is momentum, m is the mass of object and v is the speed of the object

Initial momentum

The initial momentum will be that of basketball and volleyball, Since basketball is initially at rest, its initial velocity is zero

p_i= m_bv_b+m_vv_v=8*6+0.6*0=48 Kg.m/s

Final momentum

p_f= m_bv_b+m_vv_v=8*4+0.6*v_v=32+0.6v Kg.m/s\\32+0.6v_v=48\\0.6v=16\\v_v=16/0.6=26.66666667\approx 26.67 m/s
