What is the velocity of a skateboarder whose momentum is 100 kg-m/s and mass is 15 kg?
The velocity of a skateboarder who momentum who is a 100 kg is 6.67 m/s. Solution: p=mv; 100Kg m/s =15Kg x v; v=6.67 m/s.

Questions asked by the same visitor
An object has a momentum of 4,000 kg-m/s and a mass of 115 kg. It crashes into another object that has a mass of 100 kg, and the two objects stick together. If the momentum is conserved, what is the new velocity of the combined object? Round to the nearest hundredth.

An object has a momentum of 4,000 kg-m/s and a mass of 115 kg. It crashes into another object that has a mass of 100 kg, and the two object stick together. If the momentum is conserved, the new velocity of the combined object is 18.60 m/s.
Solution:
Momentum=mass * velocity;
P = m * v;
4000 = 115 * v;
v=4000/115 =34.78 35m/s;
Total mass = mass of initial object + mass of second object;
Total mass = 115+100 = 215kg;
v = p/m = 4000/215 = 18.60 m/s.
An object has a mass of 13.5 kilograms. What force is required to accelerate it to a rate of 9.5 m/s2?

128.25 N force is required to accelerate it to a rate of 9.5 m/s2.

Solution: force = ma
= 13.5 kg x 9.5 m/s2
= 128.25 N.
