Question

IM LATE FOR A DATE AND I GOTTA GET THESE DONE!! PLEASE HELP!!


If a force of 16 N is applied to an object with a mass of 5 kg, the object will accelerate at ?????

An automobile with a mass of 1239 kg accelerates at a rate of 4 m/s² in the forward direction. What is the net force acting on the automobile?

What is the weight on earth of a girl with a mass of 35 kg?

A 95 kg zebra is traveling 8 km/hr east. What is the zebra’s momentum

Answer 1

1. To solve this problem you can use the formula:
Force = mass × acceleration
16 = 5 × a
16/5 = a
3.2 m/sec^2 = acceleration

2. To solve this formula use the same formula that was given above:
F = ma
F= 1239 kg × 4m/sec
F = 4956 N

3. To solve this problem use the formula:
Weight = mass × gravity
W = 35 × 9.8
W = 343 N

4. To solve this problem use the formula:
Momentum = mass × velocity
M = 95 kg × 8 m/s
M = 760 kg × m/sec

hope this helps :)
