To calculate the acceleration of the truck, we use the equation of motion
Here, v is final velocity of the truck, u is initial velocity of truck, a is acceleration of the truck and t is time taken.
Given, u = 6 m/s, v = 14 m/s and t = 4 s.
Substituting these values in above equation, we get
.
Thus, the truck acceleration is
Answer:
22) 5.6 Kg.m/s
23) 0.067 Kg
24) 1.16 m/s
Explanation:
Momentum is found by multiplying mass and velocity
P=mv where P is momentum, m is mass of object and v is the velocity
22
Given
Mass, m=2 Kg
Rate, v=2.8 m/s
Relationship
P=mv
Solution
P=mv=2*2.8=5.6 Kg.m/s
23
Given
Momentum, p=0.1 Kg.m/s
Rate, v=1.5 m/s
Relationship
P=mv and making m the subject then
